I am new to this site. I live in Mesa, Az, 30 miles east of Phoenix. My pool is a 1 year old, plaster, 8500gal, Hayward cartridge filter w/1 hp pump with selectable on/off sprayer-aerator and 2 foot wide direct-dump water spill. I have only recently taken an interest in caring for the pool, this is all new info to me. The CYA and CH levels (100+ and 1200+ respectively, were out of control). I did a COMPLETE drain and refill on 3/2/10, the fill water readings were as follows: FC-1.0 CC-1.0 TC-2.0 pH-7.4 TA-140 CH-410 CYA-0.00 Temp-67'F. After adding muriatic acid, 10% liquid chlorine and 1 gal liquid CYA, the levels as of 11:00AM 3/10/10 are: FC-3.0 CC-0 TC-3.0 pH-7.7 TA-105 CH-420 CYA-34 Temp-65'F. The pool, currently, is sparkling clear.
I have two concerns: 1) my pH seems to continually rise, for which I add muriatic acid and have become very judicial as to how much I run the aerators and, 2) at what levels should I keep the pool when it becomes +/- 110'F and extemely sunny this summer?
