Finally got my pH up to 7.2, but keeping FC levels up has been tough. Dumped a gallon of bleach in this morn so we could go for a swim. By the afternoon, FC was back to zero. The solid CYA in the sock trick works well. It was dissolved in abt 48 hrs. Need to get more. I loaded up the chlorine dispenser with some pucks to try an keep some FC (and a little more CYA) in the pool during the week. Thx for all the help.
