it's expensive and a hassle to drain water, replace, dose it all back up with salt, borates cya.
Here are the current numbers, SWG in a gunite pool:
CH: 600 and climbing!
Pool Calc does not raise any red flags - mild CSI positive. I watch for Calcium buildup around the water line and on the salt cell very closely, no issue. Normally i let the pH climb to about 7.8, then nuke it with pool acid back down to 7.6.
So - tips or tricks to deal with high ch? just keep an eye on pH, TA and make sure the Calculator is happy?
thanks & happy swimming!
