Also to know is, how do I raise the free chlorine in my saltwater pool?

Shocking a Saltwater Pool To effectively shock the pool, you mustquicklyraise the free chlorine concentration to 10ppm ormore, and you do this the same way as you would in aconventionalpool -- by adding chlorine. You can usecalciumhypochlorite, sodium hypochlorite orchlorinetablets.

Why is there no chlorine in my saltwater pool?

If the pH is too low, the waterbecomescorrosive and chlorine escapes the water.Ifthe pH is too high, it may cause mineral builduponthe pool walls, making the chlorine will belesseffective. The proper pH level is 7.2 to 7.6.Thealkalinity should be kept between 80 and 120 ppm to helpbalancethe pH.

Should you shock a saltwater pool?

It's absolutely okay to shock your saltwaterpool, and is actually pretty important! Runningyourpool's super-chlorinate feature too often is hard onthemotor and will cause it to wear out faster. Thesuper-chlorinatefeature will not always kill all the algae or cleanup thepool water as effectively as poolshock.

Using liquid chlorine raises the pH ofthewater.
Liquid chlorine does not raise pH.Whenadded to water, liquid chlorine (which has a pHof13) makes HOCl (hypochlorous acid – the killing formofchlorine) and NaOH (sodium hydroxide), whichraisespH.

How much baking soda do I add to my pool?

Use only 2 pounds (910 g) of baking sodaperday.
Adding too much baking soda to thewaterat a time could raise the pH of the water. Let thebakingsoda settle and mix with the water beforeadding more.If you need to raise the alkalinity further,wait until the nextday to add more bakingsoda.
