HELP - High TA ph CH

[AnnaK]

Welcome to the Pool Forum!

I have some questions for you:
What kind of pool do you have? Vinyl liner? Concrete/gunite?
How do you test? Pool store? Strips? Test kit? If you use a test kit, what kind?


According to Ben's Best Guess Chart you need to maintain FC = 10 ppm at the very low level of stabilizer you currently have. You cannot fix a green pool with one or two doses of chlorine. It's a process and takes some time and patience.

If you have a vinyl liner you don't need the calcium so just use bleach as your chlorine source and never mind the cal-hypo.

Please take a look at the Pool Calculator. It will tell you how much bleach to add to maintain the FC at 10 ppm. Keep the pump running, brush your pool, backwash/rinse the filter when the pressure goes 8 or so points above normal. You are done shocking when an overnight chlorine test shows a loss of 1 ppm FC or less.

Keep filtering, brushing, and adding chlorine, and get some stabilizer in there—if your current test results are correct the chlorine you add is being eaten up by sunlight and not doing much good. Use the Pool Calculator to tell you how much CYA you need to get to 50 ppm, then add half that amount to start with.

Let's clean the algae up first, then we can drop the pH (and the TA). The cloudiness of the water indicates the algae are not yet all gone.
