    We are also having issues with Ph jumping up half a point in one day. I'll adjust to 7.5, then the next day it is up to 8.0. FC is also rising, and the SWG is at the minimum setting. Current numbers are: FC at 7.5, Ph at 8.0, TA at 80, CYA at 80. SWG salt reading at 2800, salt test shows 3200. It has been fairly warm, so pool wide open during the day. Pool at 82 deg. Suggestions on what to check on or do next?

    Re: Whidster

    Have you had any aeration besides the swg? Has it been windy? You may need to let your TA drop a little can go as low as 60 ppm TA if needed.

The SLAM process is not finished until: 1. CC < 0.5 ppm, 2. An OCLT < 1.0 ppm and, 3. The water is crystal clear.
