Inground pool replastered last year 3/14, Santa Barbara city fill water hard, CH 400, last august it was 475+-, slacked off on CH testing over winter, probably let the ph get to high, now at 725+-.
current reading
TA 110
PH 7.5
CYA 35
FC 5-6
CH 725
CSi .3 (high end of the "ok" range)
Water is crystal clear, we're in a major drought here in SoCal, really don't want to dump half of 14,500 gal to get the CH down to the 570+- range, and refilling entirely would be nearly immoral given the drought conditions.
What are my best options to keep CH from climbing any more?
thanks, Brian
