Well I havn't replied for a while because I had the Taylor 2006 kit on order. I received it the other day and am underway testing the pool. The booklet says to start with balanced water before bringing the chlorine/cya up to par so I began by testing total alkalinity. Total alkalinity was over 250 ppm which I guess I expected. I am in the middle of adding muriatic acid over a few day period, 1 gallon yesterday and another today. The pool is probably around 25,000 gallons, I think I'll take a good measurement tomorrow to be sure.

Anyway, thanks in advance. Any suggestions on getting started using this testing kit would be great. I guess my plan is to bring down total alkalinity and pH and then move back to bringing Chlorine/CYA into check. I am very curious to know why I see basically NO algae formation or any visual indications the pool isn't OK...
