Sodium Hypochlorite

Pool Chorine

It has a nice yellowish color, is stronger but chemically identical to regular grocery store bleach, and has 10 – 15% available chlorine and a pH level of about 13.

This liquid swimming pool chlorine is the choice of many pool owners because it produces an excellent cleaning agent called hypochlorous acid when it comes in contact with water. It can be poured directly into the pool but it’s recommended by many pool experts to first dilute the Sodium Hypochlorite in water.

The best way to add liquid swimming pool chlorine is to start in the deep end of the pool and walk it around the perimeter. You need to avoid contact with liquid swimming pool chlorine because it will bleach out clothes and may cause burns if not properly handled.

Most commercial indoor pools use liquid chlorine or Sodium Hypochlorite because it seems to be more convenient to have big 55 gallon drums filled with pool chlorine and many commercial indoor pool systems are automated which makes it even easier to have the swimming pool care consistent.

Liquid swimming pool chlorine has a shelf life of about 1 year. After that it will continue to degrade.

Remember to read the manufacture’s labels.

Swimming pool chlorine will degrade rapidly and because of this you’ll need to keep an eye on your Cyanuric acid level. Cyranuric acid is the stabilizer of your chlorine and you’ll want to keep the level between 20 -40ppm.

One of the best ways to add cyanuric acid to you pool is with chlorine tablets. You'll want to keep this level between 20-40ppm, or about 7.5% of your free available chlorine.

Example: Your chlorine level is 2.5ppm. Take 2.5 divided by 7.5% and you get 33. Keep your cyanuric acid level between 30-33ppm.Also, you'll want to do a residual chlorine demand test.

By keeping an eye on your cyanuric acid level, your pool chlorine will do it's job properly and you may not need any extra swimming pool chemicals.

1. What is swimming pool chlorine?
Chlorine is nothing more than a sanitizer of your pool. It comes in either a granular or liquid form. If you choose, there are many non-chlorine and bromine sanitizers on the market.
2. When should I test my pool chlorine?
Swimming pool chlorine should be tested in either late afternoon or early evening.
3. Where should I test my chlorine?
You should test your chlorine in the deep end of the pool or at the furthest place from the swimming pool filter.
4. Why should I test my swimming pool chlorine?
Chlorine, as the sanitizer of your pool, needs to be checked on a regular basis (at least once per week). You need to have enough chlorine in the pool to clean the water and destroy any bather waster and/or organic matter. Keeping your pool chlorine level at 1.0ppm-3.0ppm should accomplish this.
5. How do I test my swimming pool chlorine?
You need to follow the manufacturer’s instructions if you’re using a dropper system or Test Strips. If using the dropper, simply hold the vial upside down over the water and go straight down about 1 foot. Turn the vial over and come straight back up and follow the dropper directions. If using a Test Strip, get a clean cup and do the same procedure as using a vial.

Once you have your water sample, dip the Test Strip into the water for the reading and compare with the accompanying chart. And that's it. See how simple it is?

Just follow these guidelines for Sodium Hypochlorite and you'll be the envy of the neighborhood.
