    Crazy idea to reduce CH

    I was just sitting at work, reading the boards with nothing better to do and I got to thinking.......

    When the ph gets high in my pool (7.8 to 8.0), i get white flakes on the SWG cell and they flake off when the cell reverses polarity. From what I have read, the flakes are primarily calcium.

    What if I intentionally let the ph get high so this occurs, and I put a sock in front of the returns to catch the flakes?

    Haven't I caught the calcium and thus reduced the CH?

    Not that I need to, my CH is where I want it right now, but just a thought???

    That can work, but it will be slow and risks damaging the SWG.

    Would that not also run the risk of the calcium scaling the entire pool? Not just the SWG? ... might be a pretty fine line to tread.
