I just drained half my pool because of CYA being to high. When I check for calcium hardness it’s telling me I’m at 150. I want to bring it up but am hesitant because of AZ being notorious for having hard water. I check the fill water and it comes out to 25ppm. Is there anyone in Surprise that has tested their fill water? Should I raise my CH or just run a higher PH to keep the CSI in a more comfortable range?
