Understand Pool Chlorine & Proper Swimming Pool Shock Treatment For Inground, Above Ground & Salt Water Swimming Pools.
Your swimming pool water chemistry must be met for your chlorine to work properly.
It's the most widely used and one of the more cost effective ways for disinfecting.
This is of the utmost importance in properly balancing your pool water chemistry.
Chlorine is the sanitizer and oxidizer for the pool water and should be kept at 2 - 4ppm.
Its uses can include
Calcium Hypochlorite - Calcium hypochlorite and swimming pool care.
Liquid Sodium Hypochlorite - It's a great alternative to calcium hypochlorite for places with hard water and high calcium hardness.
Chlorine Allergy - Chlorine allergy and swimming pool water chemistry.
Chlorine Demand - Chlorine Demand and swimming pool water chemistry.
Chlorine Tablets - Your Chlorine Tablet (Pool Stabilizer/Conditioner) Info. For The Pool Perfect For You.

Test Your Chlorine
FC - TC - CC?
The dangers include:
You should not add this sanitizer until your pool pH and total alkalinity are correct. When your pH level is under 7.0 the chlorine becomes too active. If your pool pH is over 8.0, it becomes less than 25% active. A proper balance of pH and alkalinity using muriatic acid (pool acid) will ensure proper sanitizing.
Your Pool's FC
In the hot summer months your sanitizer can degrade rapidly. The sun will wreak havoc on your pool and for this reason any adjustments should be done in late afternoon or early evening hours.
This allows enough time for it to go work immediately and start sanitizing your pool. It should be either broadcast (Calcium Hypochorite) or poured (Sodium Hypochlorite/ liquid) evenly, starting in the deep end and kept at 2 - 4ppm.
If you have an outdoor pool and you're using it up like crazy I would then encourage you to check your cyanuric acid (pool stabilizer) level. Too little, below 20ppm, and your pool chlorine will hit bottom. Too too much cyanuric acid, above 70 - 80ppm, and it can't do the job.
One of the best ways to add cyanuric acid to you pool is with chlorine tablets. You can also use granular chlorine like sodium dichlor or trichlor. The range for CYA is 30 - 50ppm.
If you have one of the many kinds of small swimming pools or kiddie pools, just a tiny bit is needed to keep them sanitized.
