Why would certainly you want to use bleach instead of swimming pool chlorine?

If you’ve seen the news or tried come buy swimming pool chlorine recently, you’ve most likely noticed that there’s a chlorine shortage walk on.

If girlfriend can discover pool-grade chlorine, it’s more than likely a same bit much more expensive than you remember. If you can’t find any, you will do it still require some means to store your pool clean.

Let’s take it a look at the pros and also cons of using bleach rather of chlorine in this article... Yet first, let’s begin by exploring what bleach actually is and also how it different from the pool-grade chlorine you’re used to.

Bleach vs. Swimming pool chlorine: the basics

First, let’s clear something up: bleach is chlorine. Pool-grade chlorine and a jug that Clorox are essentially the very same thing, chemically. However, they’re no made with the very same concentrations the chlorine.


Pool-grade chlorine, which you deserve to usually to buy in tablets, granules, or together a liquid, has tendency to be obtainable in formulations of between 65% and virtually 100% chlorine. Pure chlorine is well-known as hypochlorous acid.

Most well-known pool-grade chlorine is formulated as calcium hypochlorite in granule or tablet computer form, which has tendency to be on the lower end of the concentration range. Countless tablet-based treatments room formulated as trichloro-s-triazinetrione, or tri-chlor. A tri-chlor tablet can deliver virtually 100% pure chlorine when dissolved in pool water.

A jug the bleach, prefer Clorox, is largely water. Bleach contains around 5% come 6% salt hypochlorite, which way roughly 95% of your jug the bleach won’t execute anything beneficial to clean your pool. Some bleach formulations may incorporate colorings and also fragrances, which can negatively influence the quality of your swimming pool water.

Liquid chlorine therapies are additionally mostly water-based, but should frequently have at the very least 10% sodium hypochlorite in a equipment without unwanted color or fragrance additives.

Can you usage bleach rather of chlorine?

Short answer: yes.

Longer answer: it relies on the formulation.

The label on every bleach bottle must tell you the ratio of salt hypochlorite (and accessible chlorine) in the bottle to every little thing else. A greater percentage is typically better, together you’ll need to use less bleach to treat your pool.


You’ll also want a formulation through no fragrances or various other chemicals. You do not do it be dyeing your pool water or making the smell favor a summer breeze.

Many online retailers incorporate label details for chemical commodities like bleach, so girlfriend can inspect both the chlorine concentration and for the visibility of any kind of other chemistry and/or additives prior to buying.

How to usage bleach to sanitize and disinfect your pool

Bleach, like any other sort of pool treatment, is finest used in specific concentrations -- the is, you’ll want to have the ability to detect a certain amount of chlorine in your swimming pool water. As well little, and also you won’t efficiently sanitize your swimming pool water and also surfaces. Also much, and also your pool water might become too harsh to use.

The ideal variety for included chlorine is between one and also three parts per million -- it is between 1-3 ppm in an ext scientific parlance. If you aim because that 2 ppm, girlfriend should offer yourself enough wiggle room in one of two people direction.

Clorox chin recommends using in between 100 and also 200 ounces the regular-strength bleach every 10,000 gallons of swimming pool water -- one gallon is 128 ounces, and many bottles of bleach are easily accessible in one-gallon or half-gallon sizes.


Pool specialists tend to recommend much more conservative amounts of bleach. I’ve seen recommendations varying from one quarter of a gallon every 10,000 gallons of swimming pool water, i m sorry supposedly raises chlorine levels to 2.5 ppm, to one gallon every 30,000 gallons of swimming pool water, for around 2 ppm the chlorine.

Most referrals assume you will do it be using standard bleach, which is around 5% to 6% chlorine. If you’re making use of “concentrated” or “extra-strength” bleach, or any other formulation over the usual 5% to 6% ratio, you’ll must use different amounts.

Chlorine division down as soon as exposed to sunlight, i beg your pardon is why chlorine-based swimming pool treatments often tend to include an included stabilizer.
