My pool is green and has been most of the summer. I've tried the pool store treatments to bring down the pH but they haven't worked. On their advice I have treated for phosphates, used algeacide, multiple shock treatments, etc. I've been studying the Pool School info, so I am ready to SLAM the pool, but need to adjust the pH first. Today I added 3 quarts (96 ozs) of muriatic acid but to no avail. My test results are:
pH 8.0 acid demand 5 drops to lower to 7.0 (I know that's too low but I accidentally added an extra drop)
This is my first time using the test kit so I hope I interpreted it right, but it seem in line with pool store test and strips.
Any ideas that may help?
