One of the things that pool owners must do to maintain the water in the pool is to make sure it has enough chlorine. Not putting enough chlorine can actually be quite dangerous because it can allow microorganisms and contaminants to stay in the pool and possibly cause unwanted problems.

Having too much chlorine on the other hand is also dangerous simply because it can cause irritations and a lot of discomfort to the swimmers. The only way you can keep the pool safe to swim in and contaminant-free is to make sure that the chlorine levels in the pool is at acceptable levels.

When it comes to adding chlorine to the pool, you should never try to do so without making the right calculations. Please keep in mind that the amount of chlorine you need to use will all depend on how big the pool is as well as how much chlorine is already present in the pool.

What Does Shocking The Pool Mean?

Shocking the pool is a process that you need to do with the help of chlorine. Unlike what you might have heard, it does not require you to buy specific products that have the “shock” label and of course, you should not use electricity to literally shock the water.

The objective of shocking the pool is to make sure that it contains a high amounts of chlorine so that all the contaminants and microorganisms will die. Shocking the pool is also an effective way to remove the algae that has been growing inside the pool. However, keep in mind that too much chlorine can cause irritations.

You cannot use the pool when you are shocking it. You will basically need to raise the amount of free chlorine inside the pool by adding excessive amounts of chlorine. What most people fail to understand is that if they are actually shocking the pool, albeit unintentionally, they are putting in too much chlorine.

How Much Liquid Chlorine To Add To A Pool?


So you can safely add chlorine to your pool, you should know how many gallons of water your pool holds and what kind of product you are going to use. You should try to know exactly how much chlorine the pool currently has and how much chlorine you want it to have.

For example, you tested the chlorine level of the pool and found out that it has very little chlorine in it. You are then planning to put in at least 2 parts per million of chlorine. You know that the pool can hold as much as 22,000 gallons of water. However most chlorine products are based on a 10,000 gallon pool.

This is why you need to divide it by that standard. So 22,000 divided by 10,000 is 2.2. The next thing you need to figure out is how much product you need to use to raise the chlorine level by 1 ppm. In most cases, this is already provided by the product manufacturer in the form of a table.

Most chlorine products are in liquid form and they contain as much as 12% chlorine. In most cases, you will need to use 10.6 ounces to raise a 10,000 gallon pool to 1 ppm. Now that you have the numbers, you should multiply the ppm by how many 10,000 gals. it contains and by how many ounces you need.

Using the example, you should get 2 X 2.2 X 10.6 = 46.64 oz. This means that you will need to use as much as 46.64 ounces of chlorine in order to raise the chlorine level of your 22,000 gallon pool to 2 parts per million. This calculation will help you determine how much liquid chlorine to add to the pool.

Instead of trying to guess and relying on estimates, I highly recommend that you try to do the math properly so you can avoid shocking your pool unintentionally and having too little or too much chlorine. Keep in mind that more work has to be done if the levels are not right.

So you can make sure that the chlorine levels are in the proper levels, do chlorine testing first to know how many gallons of water your pool holds. See how many parts per million do you want the chlorine level to be and know the specifications of the liquid product that you are using.

By finding the correct figures and adding the right amount of chlorine, you will be able to keep everyone who wants to swim in the pool safe and you can also keep the water actively seeking to destroy contaminants and microorganisms at the same time.
