My salinity has decreased today by 200 ppm over the last ten hours, measured this morning and just a few minutes ago. On Friday it was 3,000 and now I'm down to 2,600.
I have been using muriatic acid over the last two days to lower my TA, and have been aerating all the while with the return jet breaking the surface to raise the pH. So I'm wondering if this is normal due to evaporation?
(I have my SWG off as I recently started a SLAM, ran out of R-0871, and am in a holding pattern of nightly bleach additions.)
