ok Ben, ph is 7.0, alka;inity test was 100, the color went from blue to yellow, the directions on my P233 said with high FC that is normal? CYA at 70-80, using the tester from my P233, ph test was from oto drop. All new reagents. Everything that has been added since the start of season: I have added over a 1 week period 12 1 lb packs of Aqua chem shock Xtra Blue, ingredients of 63% dichlor, .26% copper,36% other. thats per 1 lb pack. 2-3" pucks Aqua chem 99% trichlor 1% other. been using walmart bleach, and this stuff from home depot from sunbelt chemicals, its called Smart Liqui-Shock, ingredients 10% sodium hypochlorite, 90% other, contains 11% available chlorine. I have been using this as my main source for the past 2 weeks to keep FC up. I havent added any "shock" product or pucks in over a week, so when I tested CYA last sunday and got 55-60 maybe it all wasnt disolved? so the 70-80 I think may be closer to being right
