    High ph due to?

    Another question for the experienced. My ph levels have been stable so far until I checked last night. It's at least 7.8 or higher. It's fairly dark. We had horrible wind and the pool is full of dirt. Will high winds and debris raise ph? What are other causes? I've read that high chlorine levels will cause it but how high of chlorine? Thanks, Ed. I'm going out to test right now and get some numbers. And vacuum it.

    Ph 7.8-8.2 I think it's closer to 8.2

    Cya 30-50 If I fill until I can't see the dot it's 30. If I compare to the 50 ppm test sample it's more like 50.

    If the FC > 10ppm, then the pH test reads artificially high.

    Aeration can also cause the pH to rise ... perhaps due to the wind?
