Last year I started the BBB method with great results. For some reason, this year, I can't keep the PH down. Its always around 8.0 and possibly higher since my tester stops to 8.0. I've been following the suggestions from the pool calculator on how much muriatic acid to add, but the PH still goes up. The pool looks great, but know this isn't right. Losing about 2ppm of FC every day if thats any indication of the problem. HELP !
FC 3.0 (normally keep it around 8, I live in Phoenix az)
