I have been having some slight issues with the PH. I started with the BBB method this year and I use the Taylor test kit. Here is where I'm at from last night.
The PH seems to keep rising slowly (not bouncing) so when I add Muriatic acid the PH drops and the TA drops. Lately the PH seem to rise over a week from 7.4 to 7.8. I thought it was the rain we had in June (over 9") but its been dry in July and still doing it. We are not using the pool a lot and the kids are older so they tend to just float to tan instead of splashing around. There is a 1/2 tube with water flowing into the pool over the edge of the pool from my small solar heater I built from irigation tubing, but not much splashing.
What can I do to get the PH lower but the TA to stay at 80 or raise it towards 100.
