Re: Test Results - Please Review
The stabilizer/conditioner is usually straight CYA. If you look at the ingredient label, it should say cyanuric or isocyanuric acid. If so, that's the stuff. You can either hang it in a sock in front of a return, or put it into the skimmer slowly, and let it dissolve on your filter (if you go that route, you can't backwash for 4 or 5 days because you'll backwash it out undissolved and have to start over). It dissolves very very slowly, so you won't be able to dissolve it enough in a bucket of water to broadcast it--although dissolving it in water as much as you can before putting it in the skimmer might speed up the process and will reduce the chance of it clogging your pipes. If you put it through the skimmer, don't bother to retest for it for at least 4-5 days--you'll just be wasting the reagent. You do need to dose with chlorine of some sort in addition to the stabilizer. All the stabilizer does is help protect the chlorine you put into the pool from being consumed by the sun. It will not significantly lower your pH. It is a weak acid. If you're happy with the liquid chlorine, then I'd just go with straight CYA and skip the dichlor. Dichlor will drive your pH down significantly, and the CYA won't.
