Calcium Affect on Salt Cell

[grottoguy]

I have the autopilot digital SWG and the directions state that my CH should be between 200-400. It also states that if CH is too high it could prevent the salt cell from being able to clean itself. It doesn't specify, however, what level of CH is problematic for the salt cell. My CH is 425 ( and thus higher than the range given) and was wondering if I should lower it by draining some of my pool to prevent this problem. My fill water is only 25 CH so I know that would be effective.

My question however is whether this is a concern at 425.

Thanks

It is not really just the CH that is the problem, it is the CSI. If you keep that slightly negative, you will reduce the likelihood of problems. This is most easily accomplished by lowering the pH.

Ok. Thanks
