15K gallon pool
So, I guess I need to lower the pH huh? Maybe add 1 cup of muriatic acid (31.65%)? I added two cups yesterday. My pH was at 8.0 and dropped to probably 7.6, but now it's at 7.8. (I should mention I have problems with the pH color chart...they're all so close).
I couldn't test CYA because the sun isn't out. I find it difficult to do that dot test.
