After putting bleach in for two days, and adding 1 pint of muriatic acid, according to package directions for my size pool, my numbers with my 6-way strips were all in the normal range for this test kit. (haven't gotten my good test kit yet) These WERE the readings at the end of that day of adding the bleach and acid:TH 200/FC 2-4/PH 7.5/TA 120/CYA 30-50... Yesterday and this mornings readings are:TH 100/ FG 5-10/PH 8.4/TA 120/CYA30-50. My ph just won't cooperate! Is it safe to add more muriatic acid? My pool water is beautifully clear and feels great! It smells great not like strong chlorine but clean and soft! You wouldn't think there was a problem with numbers at all! I just want to relax and not worry about that ph level!
