I have no idea why my CH is so high. This is our first season, and we started out with a CH of around 150.
We have nasty well water, but got water trucked in to fill the pool originally - and only added about 20 lbs of calcium flakes to that. We haven't had to fill much at all from the hose. But to be sure I tested the hose water, and the CH is only 100.
Why is this happening? I haven't used any Cal-Hypo. We have a natural rock feature, can calcium be leeched from the rocks?
I starting to notice white deposits on the hydraulic cement around the rocks and maybe a little around the tiles.
