chlorine tabs

[reitzon]

I generally use the liquid cask that I buy at the store, plus floating chlorine tablets-----NOW---the pool analys at the store says that I should stop usng chlorine tabs----because they alter the liquid that I put in.

Confused???

If the liquid you are putting in is chlorinating liquid or bleach, then it is not true that adding tabs alters the liquid you are putting in. It is true that the tabs, if they are Trichlor, will add Cyanuric Acid (CYA) to the pool in addition to chlorine and you have to be careful about having the CYA level get up too high. So that's probably what they meant (since CYA does make chlorine less effective) and it's good advice. Even better advice would be to sell you a Taylor K-2006 test kit or equivalent (one with a FAS-DPD chlorine test). That way you can measure the CYA to see when you should switch from Trichlor to chlorinating liquid.
