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???
