Sorry if this is a dumb question....
This is "scale", correct? I just bought a Taylor test kit that can measure calcium hardness. It looks like mine CH is around 625ppm. The local pool shop who has tested my water this year didn't feel I had a problem with CH. I also have a salt system and I don't know if that'll affect test results in relation to CH like it does with total dissolved solids.
So... Is it safe to assume the white build-up is a direct result of my higher than normal CH? If so, I have to drain the pool a bit and refill?
