Why Is My swimming pool Green?
There room a pair of factors why swimming pool parts and water might change into various colors, consisting of green, brown, black, purple, and also yellow. Among the major reasons that all pool owners know is birds breakout and another the very couple of know is steel staining.
You are watching: Why is my pool filter orange
1. Birds Breakout
Algae is always caused by low totally free chlorine levels and it shows up in green, black, or yellow in shade on swimming pool walls, on swimming pool floors, in the water, and also sometimes on pool equipment, depending upon which algae you are dealing with.
However, if the pool water and also parts discolor specifically when you include chlorine or shock it, and also the chlorine level is simply okay, you space not having actually an birds problem. It might instead be since of hefty metal presence in her water the is causing metal stains.
You can lug out an Overnight Chlorine Loss test (OCLT). To carry out the test, add a typical amount that chlorine to your water and take the reading. This must be done in the evening/night as soon as there is no sunshine that consumes cost-free chlorine.
Take the chlorine analysis the following morning. If tiny chlorine is offered up (0–1 ppm), the OCLT an outcome indicates the is not algae or any kind of organism that can have offered up a many chlorine (above 1 ppm). Thus, it's have the right to only be steel staining together a an outcome of redox by chlorine.
2. Hefty Metals
When heavy metals including copper, iron, silver, manganese, and also magnesium room oxidized by chlorine inside your swimming pool, pool parts and also water will revolve to various metal stain colors and some of the colour are similar to those of swimming pool algae (green and also black), specifically when just starting to grow. This might confuse inexperienced swimming pool owners do the efforts to number out in between algae breakout and metal staining.
Copper is always the most usual metal girlfriend will uncover in her swimming swimming pool water. This is due to the fact that it occurs naturally in well and also some municipal water and likewise finds its way into the swimming pool water through some chemicals we use, together as some algaecides.
Copper turns to a light green shade when oxidized by chlorine inside her pool. Other metals you may discover in her pool—especially as soon as using well water—are silver- that transforms to black, iron that transforms brown/rust, and also manganese and also magnesium that rotate to purple once chlorine is added to swimming pool water with compounds of these hefty metals.
Heavy metal Test
To be certain if friend are dealing with pool algae or metal stains in your pool, there room two alternatives you deserve to use. The easiest means is to check your swimming pool fill-water because that these metals using a test piece that supports heavy metal tests favor the LaMotte ColorQ agree 11 check kit, i m sorry takes readings the all swimming pool chemicals and common heavy metals friend can find in your swimming pool, including copper, iron, biguanide, and biguanide shock.
This article will explain why a pool turns green when chlorine is added and what you have the right to do about it.
Lo - Chlor
Copper is one of the most common heavy metals uncovered in a swimming pool, and often the reason your pool turned green after including chlorine.
Causes of heavy Metals in a swimming Pool
Depending on which fill-water you room using in your pool, a pair of hefty metals may discover their means into her pool. The most common metals in swimming pools are copper and also iron. Other steels like silver, manganese, and magnesium may only gain into your swimming pool if you are located approximately areas where these metals are mined and you are using well water come supply her pool.
Copper in specific is the many problematic metal in a swim pool, and also it will revolve to light eco-friendly when chlorine is added. When any heavy steel is oxidized by chlorine, her swimming swimming pool water, and also parts will discolor as a result of metal stain. Together a swimming pool owner, you have to know how metals get into your pool and how you can manage or clear them.
Here are the sources of most typical metals favor copper and also iron, i m sorry have greater chances of gaining into your swimming pool.
1. Including Pool chemistry With heavy Metal Components
Using pool assets with heavy metals as among the major components is among the methods you can gain them into your pool. For example, consistent use of part algaecides v excess copper will accumulate a far-ranging amount that copper equipment in a swimming swimming pool over time. This may lead to pool water transforming green once copper systems reacts through chlorine shock.
As such, it's constantly advisable to recognize your swimming pool's chemical components in detail and avoid chemicals that will cause extr problems in her pool.
2. Utilizing Fill Water native a Well
Wells are frequently known come be among the greatest sources of steels in a swim pool, especially copper and iron. Iron reacts v chlorine to form iron III chloride, which is red in color. This is why your pool may turn to brown or rusty color when chlorine is added.
3. Using steel Pipes and also Pool Parts
During the building and construction of a swimming pool, copper, iron, silver, or any kind of metal may be used in pipes and heaters. Because that instance, the use of copper components requires a most pool care. This is due to the fact that when the pH gets as well low, metal parts (especially copper) will corrode into the water, developing a copper solution. Copper then comes out of the solution when oxidized through chlorine, bring about a green color in your swimming pool water and also parts.
What have the right to You Do around It?
If you can't avoid using to fill water native the well, making use of pool chemistry made the copper as among the components, or using copper parts in her pool, you should be all set to attend to metals to stop messing up your swimming pool water.
Dealing with metals means frequent testing for metals and also performing important treatment for every metal, largely copper and iron.
I have actually been making use of Lamotte ColorQ pro 11 to bring out various tests for metals such together copper and iron. This digital check kit is accurate and also time-saving, since you deserve to test all swimming pool chemicals and common metals in your swimming pool water in simply one kit.
You should constantly filter water sourced indigenous a fine or municipal water source. Prevention is the best protection.
Steps for Clearing steel Stains in your swimming pool
To clear metal stains in her swimming pool, simply follow these steps. Ns have included links to the commodities that i use.Get your cost-free chlorine to 0.0 ppm by not adding an ext chlorine. This can take a couple of hours or days depending upon the level the FC in her water.Get your pH come 7.2 making use of pH minus.Get the pH earlier using pH Plus. Climate raise the TA utilizing an alkalinity increaser, due to the fact that ascorbic acid will alleviate both.Add chlorine come raise her FC to around 3 to 4 ppm.
How come Remove heavy Metals and also Control metal Staining in her Pool
Treating hefty metals in your pool might be the just option because that you once you have actually no various other clean fill-water cost-free of steels to usage in the pool. There room a pair of means you deserve to take care of your pool so that hefty metals such together copper and iron will certainly not impact your swimming pool when oxidized by chlorine.
Once you have an exact test kit because that metals and a few other chemicals we are about to discuss, your swimming pool will never ever turn color due to different heavy metals.
1. Filter fine Water prior to Entering the Pool
They say prevention is far better than cure. Filtering your fill water native the well will certainly be the ideal option if you desire to have less work and more swimming. This is since water sourced indigenous the well and some municipal water resources contain far-ranging amounts of heavy metals, mostly copper and iron.
And in some cases, friend may discover some more heavy metals, such together zinc, magnesium, aluminum and silver in your swimming pool water.
Each and also every metal is oxidized and also produces a systems of distinctive colour as soon as chlorine is included to a pool through these metals:Copper: produces a light eco-friendly solution or stain.Iron: to produce brown/reddish/rusty coloured equipment or stain.Manganese and Magnesium: develop purple solution or stain.Silver: develops a black color colour stain or solution.
Whichever metal is causing difficulties in her pool, you can use a pre-filter to filter the end these metals before they get in your swimming pool, whereby they will certainly most likely be oxidized by various other pool chemicals and stain your swimming pool or readjust its water colour.
Moreover, as soon as you prevent steels from her pool, you will save lots of money indigenous buying pool chemicals that are essential to take treatment of metals once they are inside the pool.
Since I started my swimming pool business, I have been making use of the Pleatco Disposable Pre-filter. I consider it the most efficient pre-filter, since my client who room using steel ridden fill-water have been sending me positive comments about saving on chemicals and also time for preserving their pools.
Pleatco's Pre-filter is also ideal because it can filter a one-time water volume of 40,000 gallons and also can quickly thread onto any standard garden hose. This pre-filter can additionally be offered for in-ground, above-ground and spas sourcing indigenous metal-laden water.
2. Making use of Chemicals to Treat hefty Metals in a Pool
The final option and the most tiresome method of dealing with metals in a swimming pool water room using chemicals. As well as being tiresome, these chemicals might be a tiny expensive and also might need extra treatment to avoid more problems. That is why utilizing them need to not be an choice if you have the right to super-filter your swimming pool water beforehand making use of a pre-filter.
Here are few chemicals you have the right to use to treat your swimming pool water to stop staining swimming pool parts and also discoloring her water. The very first chemical I will recommend is the one the absorbs steels from pool water and also is put at the skimmer basket or pump basket, and the second one suspends/holds hefty metals in a solution, and the critical one clears fresh metal through the filter.
A. CuLator Ultra PowerPak 4.0
This is my second recommendation after ~ a pre-filter due to the fact that chemicals room not included directly right into the swimming pool, however I use it top top skimmers or pump baskets. CuLator Ultra PowerPak is capable of remove 4.0 ppm full dissolved steels from 20,000 gallons of swimming pool water.
This product can be offered for up to 30 job or longer, depending upon the lot of steels in her water. It has actually an added advantage due to the fact that you have the right to use it to eliminate several metals, such together copper, iron, manganese, silver, cobalt and nickel, and can it is in used efficiently on fresh or salty water.
B. Sequestering Agents
Metal sequestrants work differently by avoiding metals native coming the end of a equipment inside a swimming pool. By staying clear of metals native separating in a solution, pool components will not be discolored and also water colour will not change.
When picking a sequestering or chelating certified dealer to use in her pool, you have to be careful. Many of the sequestrants in the market have actually a far-ranging amount the phosphate as one of the major components, and you don't require a bunch the phosphates accumulating in your pool due to high chances of scaling inside and also around the pool.
The only sequestering agent i know around without phosphate is one the I have actually been using for a when now: the SC-1000 through Orenda Technologies. Besides avoiding metal stains and pool water discoloration, the SC-1000 is also capable the removing and also preventing calcium scaling, because it controls calcium levels in swimming pool water.
C. Metal and also Metal Stain Remover
To eliminate fresh metals through the filter, you will need metal Magic by pro Team that also clears metal stains. Metal Magic is the best option compared to metal sequestrant since it almost removes fresh steels in your pool water via her filter.
This is additionally the finest option I've discovered after the CuLator ultra strength pack and also is used on a monthly basis because that preventive steps to avoid metal stains.
If girlfriend need more detailed information, inspect out my other articles:
Additionally, included listed below is a detailed video done by the river Bend pool firm explaining exactly how to usage SC-1000 to manage metals and scales in her pool.
This contents is accurate and true to the best of the author’s knowledge and also is not supposed to substitute for formal and also individualized advice indigenous a default professional.
Questions & Answers
Question: us filled ours pool v well water. Climate my boyfriend added bleach to the pool. 30 minutes later on the pool was brown. How do I settle this?
Answer: Brown stains in your pool means you have Iron metal component in her water that has been oxidized by chlorine.
To clean the brown stains in your pool, make sure your pH is not much more than 7.2 and also FC is low at 0ppm to avoid much more brown staining, placed your pool filter ~ above circulation and include 1 lb ascorbic acid for every 10,000 gallons the water targeting most stains influenced areas and also the stains will certainly disappear within 24 hours.
After clearing all the stains, before including any chemistry in your water, add initial sheep of steel sequestrant like Orendas SC-1000 or metal removers like Proteam metal Magic to prevent more metal stains. You will need consistent treatment(weekly/monthly) of metal sequestrant or steel removers walk onwards to regulate metal stains.
Alternatively, you deserve to use CuLator Ultra PowerPak in her skimmer and/or pump bucket come remove metal compounds prior to entering her pool and also prevent steel stains when you include chlorine.
Finally, measure and balance every your pool chemicals beginning with FC and Cyanuric acid, pH and also TA, and also all various other chemicals.
You can find all these mentioned assets on Amazon through over links in the very same article. If you much more details on how to clear and prevent steel stains in your swimming pool or spa, monitor this link:https://usmam.org/swimming-pools/Fixing-Swimmi...
Question: i filled my small pool through well water and creek water. When I shocked it, the turned a light green. My swimming pool store male says there’s no turning back and I have to drain the pool and also refill it and put an iron additive to the water. Ns can’t think I can’t solve this without draining the pool. What if this was a 30,000-gallon inground pool?
Answer: You have actually Copper metal in your pool and also that is Copper metal stain that is light green in colour. Reduce the pH to 7.2 and also leave free chlorine(FC) to deplete by itself to 0ppm. Girlfriend may have actually to drain your swimming pool water partially to mitigate FC to zero faster.
Add Polyquat 60 Algaecide by agree Team that is metal cost-free to avoid algae while FC is zero. Include ascorbic mountain to her pool, 1 pound of ascorbic acid for every 10,000 gallons and metal stains have to disappear. Add Metal Magic by agree Team as directed for initial sheep to remove all fresh steels in your swimming pool water via the filter, use metal Magic ~ every 1 month to remove fresh metals and also avoid an ext metal staining in the future. Right here is much more on just how to remove steel stains and also prevent metal staining in the future: https://usmam.org/swimming-pools/Fixing-Swimmi...
Question: My swimming pool turned a light eco-friendly color however has no algae. I had a local pool facility test my water and also the totally free chlorine level was 3.84 ppm through a complete of 5.32. PH 7.4. Alkalinity 110. Copper 0, phosphate 357, iron 0.2 ppm. I found 2 pennies at the bottom i m sorry were probably there because that a pair of days. Could pennies it is in the resource of my pool's discoloration? ours pool facility recommended the I add 1 lb shimmer n shock which ns did.
Answer: because it's not algae and also you have no Copper link in your water, the pennies can be the reason of discoloration. However, you need to have an accurate test kit that have the right to measure metals because having it done by the swimming pool store may not it is in reliable enough as some always give not correct readings. Light environment-friendly color method there is copper in your water. You have the right to use ascorbic acid to clear the stains before shocking your pool again if you see much more green stains you will have to either add Metal magic through ProTeam to remove the steels through the filter or add metal sequestering agent to host metal components and also avoid metal stains once you shock your pool.
Question: I included my packet the hth to my little pool, but prior to I noticed and also was currently outing the packet, the hth was the dark yellowish-orange color. Currently the pool is, so i tested it and also the chlorine was low and I included 1lb of shock through running the filter pump. It’s quiet discolored. What need to I execute at this suggest to diagnose my pool's discoloration?
Answer: You might be having actually mustard algae that appear yellow in color and also not steel stain.
short chlorine motivates algae growth. As such, all you need is lots of chlorine. I choose you to usage liquid chlorine.
Raise totally free chlorine level to 12ppm and maintain the thereby adding chlorine as soon as it drops to 8ppm at the very least twice a day until you remove algae, it might take a couple of job to remove algae.
Barack James (author) from green City in the sun on July 01, 2020:
Green swimming pool water might mean you have actually Copper metal in your water the is oxidized through chlorine. Girlfriend ascorbic acid to clean the environment-friendly metal stain. Cloudy water also means your chlorine is too low and you must fix that by adding an ext chlorine in her water.
LeeAnn Jillson ~ above July 01, 2020:
My swimming pool is 18x36 inground. I have a brand-new sand filter and sand. The chemical levels room all WNL and it has actually been vacuumed through robotic vacuum. The water is green and also has come to be greener because vacuuming. Will certainly phos totally free be any kind of help? that is also an extremely cloudy almost milky
Barack James (author) from environment-friendly City in the sunlight on June 26, 2020:
First time adding the steel magic is actually an early dose, succeeding monthly enhancements will currently be maintenance dose.
Readyforsun ~ above June 26, 2020:
When I include the metal magic need to I do the initial therapy dosage or the rountine maintain dosage since all the stains have currently been removed?
Barack James (author) from eco-friendly City in the sun on June 25, 2020:
You can include chlorine mmediately after adding metal remover. Make certain your Cyanuric acid level is also within the range.
Readyforsun on June 25, 2020:
How lengthy after I acquire stains out and add metal remover do I have to wait before starting to carry chlorine ago up?
Barack James (author) from green City in the sunlight on June 22, 2020:
You have a little amounts of steels inside her pool and you need to fix the by removed the steel compounds within your swimming pool to protect against stains.
Start by including ascorbic acid inside your pool to clean the stains that space visible, then before adding chlorine again, include metal magic by ProTeam within the pool to remove metals through the swimming pool filter and backwash and rinse her filter.
Make sure your Iron eliminate is working so that no an ext metal gets right into your pool resulting in stains once you include chlorine or once pH rises abnormally. Friend can additionally use CuLator Ultra PowerPak metal remover in the skimmer or pump basket to assist in removing metals in her water prior to entering your pool.
Readyforsun on June 22, 2020:
Hello ... I require some advice.. Ns have had actually my pool for 10 years and never had had steel in mine pool.. We have actually a soft water device that clears iron from our water.. Still we added water to pool as soon as our device was the end of steel remover and that’s wherein our problem starts!! therefore I offered citric acid and also it go an amazing job at clean the stains from the pool! yet once ns started adding the chlorine earlier it looks choose the pool has actually some staining again.. No where close to as poor but enough to drive me crazy.. Need to I carry out the whole process over again? any kind of advice would be greatly appreciated!
Barack James (author) from green City in the sun on June 12, 2020:
Happy come hear that Mike, I imply that you include chlorine during the day and measure cost-free chlorine level after 4 to 6 hours and also raise it back if it falls by an ext than 1ppm in order to stabilize complimentary chlorine level. Great luck.
Mike R. ~ above June 12, 2020:
Thanks, again, Barack!
Chlorine test this day dropped under to 0.6 ppm from yesterday's 1.5 ppm. No alters on Ph or alkalinity. The water cleared up to "sparkling clear" overnight together yesterday's chlorine and also shock dissipated.
Today, ns did provide the pool another dose the the SC-1000 and ascorbic acid and will add much more chlorine later.
However, this was all still encouraging. At least today the chlorine hadn't dropped come zero, so some progress - a measurable quantity of complimentary chlorine after 24 hours. Whoo hoo!
Will obtain the CuLator product ordered and also in the pump filter basket.
Barack James (author) from green City in the sunlight on June 11, 2020:
Hi Mike, good to listen the progress in totally free chlorine level. Continue adding much more chlorine come raise FC level to 3ppm and the cloudiness will disappear. At the same time you will certainly still require a steel sequester doses till you acquire the CuLator steel filter.
Mike R. top top June 11, 2020:
Thanks because that the fast reply, Barack!
Even with the an adverse metal tests, i did go ahead and add the SC-1000 and also ascorbic mountain yesterday.
Today i retested the Ph and also alkalinity and also both were good. The water to be still crystal clear.
After the tests, I included a chlorine based shock (2-1/2 lb.s) and also a starter sheep of di-chlor (also approx. 2-1/2 lb.s).
Again, as soon as the chlorine fight the water the dissolved and also turned green. However, today, the in its entirety cloudiness that this developed was just about half as opaque as the past dosages. At least today you could just still watch the drainpipe in the deep end. This was encouraging.
After allowing the water to circulate for around 45 minutes, i did test the chlorine levels (free and also total). The water was still cloudy, yet the free chlorine lastly measured at around 1.5 ppm (same with total chlorine - ~1.5 ppm).
So, this was a an excellent improvement. I think if over there is still a measurable lot of chlorine in the water tomorrow, I will certainly re-dose the pool through the SC-1000 and also ascorbic acid.
If needed, I'll likewise add much more chlorine to shot to obtain it back up to ~1.5ppm. Hope the chlorine test tomorrow will still present an effective amount in the water, and also I won't need to add any more for at the very least a couple of days.
If this functions out, i think using the CuLater product will certainly be alongside see if I can actually remove every little thing the steel that is in the water.
I'm quiet baffled through the an unfavorable metal test (Cu and Fe), however I guess if the SC-1000 and also ascorbic acid are working, then i won't argue through success.
Barack James (author) from environment-friendly City in the sunlight on June 10, 2020:
Since you space using fine water as your fillwater, seems to me prefer you have small amount the copper metal that turns your pool greenish when you include chlorine and also you have the right to reduce the level by one of two people draining and also refilling a section of your pool water through fresh water or using steel remover inside her pool.
But since your metal test turn negative, this could also be an algae, for this reason you have to be really sure it's steel stains and also not algae.
If sure it's metal stains ( steel stains removes up as soon as you include ascorbic acid) and draining and also refilling pool water is expensive, you have the right to lower metal levels in your fill-water one of two people by using metal filter like CuLator Ultra PowerPak in your skimmer or pump basket, or use metal remover like Proteam steel Magic inside your swimming pool in early dosage and also frequent weekly doses together directed come remove steels through your filter.
About persistent cloudy water, if her Cyanuric mountain is low too like your complimentary chlorine, you have actually ammonia in her pool and you require a many liquid chlorine to eliminate ammonia. However, before starting treatment for ammonia, you have to fix metal levels in her pool because you will certainly be making use of a many chlorine that will cause an ext metal stains.
Mike R. on June 10, 2020:
I'm in ~ my wit's end, and have no idea what my trouble is.
This year (after around 30 year of use), I'm convert my pool from Baqacil come chlorine. Because that the critical 3 seasons, we've had actually a most trouble v a white fungus cultivation in the water lines and also getting clean water has been a struggle. An easy stats:
Inground, 26K gal., sand filter, fine water (delivered with all plastic pipes). All pool pump water lines space plastic. Vinyl liner.
Before opening the pool, i cleaned mine sand filter and also added brand-new filter sand.
To switch to chlorine, we did not include any an ext Baqacil commodities when we opened the pool. I added an algicide and also shocked through a non-chlorine shock. Ns then permitted another main pump on and also filtering v the cover off.
I've balanced the Ph and also alkalinity. The Ph is in ~ 7.6 - 7.8 and alkalinity is around 250 ppm. I'm no having any type of issues keeping these numbers.
Test strips show hardness ~ above the low finish of the "good range."
Right currently my water is clear together glass. The 8' deep end looks favor it's 8" and not 8 feet deep.
However, i cannot get any kind of chlorine right into the water. End the last month, count the chlorine shock, I've added around 20 lbs that di-chlor. As shortly as one of two people the shock or dry di-chlor room added, as they dissolve, the water automatically turns a cloudy, yellowish green and also develops suspended particles. This particles will certainly filter out and / or resolve to the bottom and can be vacuumed out.
When back-washing the filter, the dirty water looks choose lemonade colored milk. The water will work out to a sparkling state.
Testing for chlorine after ~ 24 hours gives me basically 0.0 complimentary chlorine and also maybe 0.6 full chlorine. No matter just how much chlorine or shock i add, the test results come the end the same in a job or less. The immediate an outcome is the chlorine transforms a cloudy yellow-green as it's added, the whole pool gets so cloudy and also murky you can't see the bottom, also in the shallow end. Run the pump and filter lengthy enough, and... Clean water again but with no chlorine, totally free or total.
The Ph and also alkalinity remain basically unchanged, hardness doesn't change, etc. Condition quo prior to the chlorine to be added.
I thought that as soon as I review this article around metals in the water ns had discovered my culprit. Ah ha! At critical a solution!
Unfortunately, I gained my test kit (LaMotte) this particular day for copper and also iron, and also the results are essentially 0.0 for both. (BTW, the check strips room not expired.)
Out the desperation, i did add 2-1/2 qt. Of SC-1000 and 2-1/2 lb. Of ascorbic acid, and I'll try to include chlorine again morning after allowing the pump to operation for 24 hours. However, ns don't have actually high hopes.
Can you offer up any type of suggestions?
Barack James (author) from eco-friendly City in the sun on June 04, 2020:
Brown stain could mean your pool has Iron and also has to be oxidized by high chlorine levels resulting in the brown stains.
Stop including chlorine in your pool, you require Ascorbic mountain treatment once the pump is top top circulation settings to clear metal stains.
After clearing the stains, you need to add ProTeam steel Magic to remove any remaining steel compounds so the you don't get an ext stains once you add chlorine.
Brenda together Sanchez on June 04, 2020:
Hi ns shock my pool for algae difficulty ... Add the flouccant and also now my pool is brown color. Haven't vaccum the pool, as the instruction claimed . Yet is this typical that it turn brown?
Barack James (author) from green City in the sunlight on may 27, 2020:
Rob, sorry for the late response, we had actually a small hitch v comments section yet it's currently resolved.
The green tint on her water might be together a result of Copper metal being oxidized through high chlorine levels.
Seems you have actually some Copper aspects in your water perhaps as a result of utilizing Well water in her pool, utilizing Copper based Algaecide or you have actually a Copper based warmth exchanger.
To clear the green tint on her water, add ascorbic acid however remember to reduced or wait till FC level is 0ppm for quicker results.
To avoid an ext stains when cost-free chlorine is high or pH is low, you need to reduced Copper steel level in your swimming pool by draining and also refilling a part of your swimming pool water, alternatively, girlfriend can add metal remover like ProTeam metal Magic come remove steels through the filter and backwash her filter.
Here's more on exactly how to clear and metal stains: https://thesummerpools.com/blogs/blog/how-to-clear...
Rob on may 22, 2020:
Thank you for your rapid reply to my inquiry from previously today. Come clarify a bit (no pun intended) - utilizing a test piece this morning mirrors my chlorine level has actually junped way up after shocking critical night so ns assume that is not algae - I can be wrong.
The water is still an extremely clear although there is a noticable green/teal tint to it this day vs. Yesterday (pre shocking).
I execute not see any staining on the return or ladder - just a green/teal tint to the water, much more prominant in the deep end
Barack James (author) from environment-friendly City in the sunlight on may 18, 2020:
Don, it seems the level of copper components in your water is as well high and also that is why you gain green stains as soon as you add chlorine or once pH is too low.
To avoid adding more metal stain sequestrants, you deserve to reduce the level the copper in your swimming pool by draining and also refilling a fifty percent of your pool water, or even much more than a fifty percent if friend can.
Buying a new Copper heater is no the systems unless the is rusty or something. If you usage copper heater in your pool, copper compounds will accumulate in your water end time, and also you have the right to only control green stain by draining and also refilling your pool water, or using a metal sequestrant, or a metal remover.
Just mental to keep your complimentary chlorine and pH within the encourage range, and also keep your water well balanced by measure Copper metal level in your swimming pool water at least once a month and drain and also refill your swimming pool water if the level is high.
If draining and refilling your swimming pool water is also expensive, friend can include a steel remover favor Proteam steel Magic in your water to eliminate Copper metal components through the filter, climate backwash and rinse your filter.
Don on might 18, 2020:
I’m being told the copper warmth exchanger on mine heater might be going bad and also keeps reintroducing copper right into my pool , I have treated my pool v ascorbic acid and also metal the end 4 times as directed and also each time it has actually cleared the pool up an extremely nice , just to have the environment-friendly tint return ~ we include chlorine. No one deserve to tell me how to phone call if that is the heater . Please assist , a new heater is $2800 and also I’ve invested $325 top top chemicals and also still have the worry . Give thanks to you
Barack James (author) from eco-friendly City in the sun on may 12, 2020:
Bright eco-friendly colour method your water has Copper metal and also has to be oxidized through chlorine. You have the right to use Proteam steel Magic to remove Copper link via the filter come avoid much more green stain.
If you setup to usage the cook copper pipe, girlfriend will have to include a offered amount the Proteam steel Magic ~ above a monthly communication to avoid an ext metal stains.
No, it's not safe come swim in a swimming pool with metal stain.
Jessica Wright on may 12, 2020:
My husband and kids collection an experiment up to warmth the pool water via boil copper piping, the pool water is now bright grren. 2 things exactly how do we remove that and also secondly is it safe to swim in
Barack James (author) from environment-friendly City in the sunlight on April 11, 2020:
Before including chlorine, you should be sure you are handling green algae and also not copper metal stains. If your swimming pool turned light environment-friendly only after adding chlorine, girlfriend are handling metal stains and you require ascorbic acid treatment which friend can access via above link in this article.
However, if you understand it's green algae, you need to add lots of liquid chlorine come raise and also maintain complimentary chlorine level between 8-12ppm till you see no much more algae; meaning you will need to test your FCL in ~ least an ext than once a day and also top it up to 12ppm if that goes listed below 8ppm till you clear every the agae.
