You are watching: How much bleach for 10000 gallon pool

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

If you’ve watched the news or tried to buy pool chlorine recently, you’ve probably noticed the there’s a chlorine shortage walking on.

If you can uncover pool-grade chlorine, it’s probably a fair bit more expensive than you remember. If friend can’t find any, you’ll still require some way to save your swimming pool clean.

Let’s take it a look in ~ the pros and also cons of utilizing bleach instead of chlorine in this article... Yet first, let’s begin by experimenting what bleach actually is and also how it differs from the pool-grade chlorine you’re used to.

Bleach vs. 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 v the same concentrations of chlorine.


Pool-grade chlorine, i m sorry you have the right to usually buy in tablets, granules, or as a liquid, often tends to be accessible in formulations of between 65% and virtually 100% chlorine. Pure chlorine is well-known as hypochlorous acid.

Most famous pool-grade chlorine is formulated as calcium hypochlorite in granule or tablet form, which often tends to it is in on the lower end of the concentration range. Numerous tablet-based treatments space formulated as trichloro-s-triazinetrione, or tri-chlor. A tri-chlor tablet computer can deliver nearly 100% pure chlorine when dissolved in pool water.

A jug the bleach, prefer Clorox, is mostly water. Bleach contains around 5% to 6% sodium hypochlorite, which means roughly 95% of her jug that bleach won’t perform anything beneficial to clean your pool. Part bleach formulations may include colorings and fragrances, which deserve to negatively affect the top quality of your pool water.

Liquid chlorine treatments are also mostly water-based, yet should commonly have at least 10% sodium hypochlorite in a systems without unwanted shade or fragrance additives.

Can you usage bleach rather of chlorine?

Short answer: yes.

Longer answer: it depends on the formulation.

The label on every bleach bottle need to tell girlfriend the proportion of salt hypochlorite (and available chlorine) in the bottle to whatever else. A higher percentage is typically better, together you’ll need to use much less bleach come treat her pool.


You’ll also want a formulation through no perfume or various other chemicals. You shouldn’t be dyeing your swimming pool water or making the smell prefer a summer breeze.

Many virtual retailers encompass label info for chemical products like bleach, so you can examine both the chlorine concentration and also for the existence of any type of other chemicals and/or additives before buying.

If you want to save extra bleach approximately for future treatments, make sure you save it in a cool, dry place indoors. Nothing leave her bleach jugs outside!

How to usage bleach come sanitize and also disinfect her pool

Bleach, like any kind of other kind of swimming pool treatment, is finest used in particular concentrations -- the is, you’ll want to be able to detect a details amount of chlorine in your pool water. Too little, and also you won’t efficiently sanitize your pool water and also surfaces. Also much, and your pool water might become too harsh to use.

The ideal range for included chlorine is in between one and also three components per million -- that’s between 1-3 ppm in an ext scientific parlance. If girlfriend aim for 2 ppm, friend should provide yourself enough wiggle room in either direction.

Clorox chin recommends using between 100 and 200 ounces of regular-strength bleach per 10,000 gallons of swimming pool water -- one gallon is 128 ounces, and many party of bleach are available in one-gallon or half-gallon sizes.


Pool specialists tend come recommend much more conservative amounts of bleach. I’ve checked out recommendations ranging from one quarter of a gallon per 10,000 gallons of pool water, i beg your pardon supposedly raises chlorine level to 2.5 ppm, to one gallon every 30,000 gallons of pool water, for about 2 ppm of chlorine.

Most recommendations assume you will do it be using traditional bleach, which is about 5% come 6% chlorine. If you’re using “concentrated” or “extra-strength” bleach, or any type of other formulation over the common 5% come 6% ratio, you’ll need to use various amounts.

You might also want to take into consideration using a salt water system rather of chlorine-based treatments.

Remember when I told girlfriend to store your bleach indoors?

Chlorine division down when exposed to sunlight, i m sorry is why chlorine-based pool treatments have tendency to include an included stabilizer.

Adding cyanuric mountain to your pool as soon as you include bleach (or some various other chlorine treatment) will prevent the chlorine from breaking down in sunlight and becoming useless because that disinfection and also sanitization.

Fiberglass swimming pool shells need to include thorough dig specs through length, width, depth, and the volume of water (in gallons) it should hold when full.

The formula because that calculating the gallons in a typically rectangular pool, consisting of freeform pools with much more or less rectangular structures, is:

Length x width x typical depth x 7.5

Through 12 customs in a foot, you must calculate inches as a portion of 12 rather than just using the inches after her decimal point -- 9 the 12 is 0.75, therefore the calculation for the I30 is:

30 x 14 x 4.75 x 7.5 … or about 14,960 gallons. (14,962.5, to it is in exact.)

The I30’s true capacity is actually simply 7,950 gallons, because it has actually a huge tanning ledge and ample bench seating.

Most pools will certainly probably have actually a true volume well below the estimates you’ll obtain from this formula, due to the fact that they’re likewise likely to have shallow-water features and forms the aren’t straightforward to measure up or account for.
