I haven't yet had time to go through all the PoolSchool materials and I have a question about my PH.
Just took readings and I have the below... PoolCalculator says ~180oz bleach to get to 9ppm (which I think is right given my CYA). We've run the pump quite a bit in the last couple of days.. would that aeration lead to the high pH? So I had been adding muriatic acid to reduce pH but I'm all out. Do Borax and Baking soda both work to raise pH (because I have both on hand).
Recommendations on the pH level given my below numbers? Thanks!
