Re: My Green Pool Saga - Help!
CYA is cyanuric acid/stabilizer/conditioner. 99% of the "pucks" or "sticks" you get now a days have CYA in them (if the ingredient starts with "trichlor", then they've got CYA added to them). TOO much CYA can become a very serious pain in the you-know-what when it comes to keeping your pool sparkling clean. You do need SOME CYA in your pool though to keep the chlorine from getting "eatten up" by the sun during the day. If your pool store uses the strips, fire the pool store...find another one. You need to look for a drop based test kit that tests for the following:
FC - Free Chlorine
CC - Combined Chlorine
It's best to have both the drop based kit (OTO) and the (DPD-FAS) powder test - the DPD-FAS tests will test up to about 50 PPM for chlorine, which is what you'll need to test accurately for your "shock" levels.
TA - Total Alkalinity
CA - Calcium Hardness
pH - pH (phenol red drop based test)
CYA - Cyanuric Acid/Stabilizer
If your pool store doesn't carry the kits that test all that, sometimes Wal-Mart will carry tests that test all those things, if you've got an ACE Hardware around sometimes they will carry them also. Other than the test kit Ben sells on the Poolsolutions web site (sister site to this forum), the next best is the Taylor K2006.
