Today test results.
Temp: 83
FC: 7.0
CC: .5
PH: 8.0
TA: 90
CH: 520
CYA: 45
Borate: 50
CSI: 0.57
Water is crystal clear, I add muriatic acid once a week to keep PH at 7.5, it likes to settle around 7.9-8.0 But my concern is why CH gets higher and higher. I test CH once a month. On May 1st CH was 340, Jun 1st CH was 400, Jul 1st CH was 420, now its 520.???
I don't add any calcium products, only 32oz. of bleach once a day & 45-55oz of muriatic acid once a week. My home faucet water tested CH:70ppm. My guess, CH is coming from topping off pool every other day.
With CH that high, I need to keep PH on the low side to balance CSI at zero. But once again, my water is clear with the very high CH.
