I was living the high life for a while, but now my results are wonky. I'm guessing my SWCG is turned up too high (I think it's set at 7 but need to double check). Hopefully my PoolMath link works and you're able to see my results. But here they are:

FC 12
pH 7.8
TA 70
CH - not tested, but 6 days ago was 175
CYA 40
Salt 2080

Annnyywaaaayyyyy. Is it ok to add stabilizer with a solar cover on? The cover has been on for a few days, and will likely stay on a few more days.

Plan: turn down SWCG, let the sun work (can it work well with the cover on?) and add stabilizer tonight, turning the pump back on for overnight. Yay or nay?

Thanks!

Looks like low salt too. Home Depot and Lowes were sold out but Lowes still had the water softener kind in the plumbing section. Just make sure its pure with 'no additives".

For the FC i would just leave the cover off for 2 or 3 days. It will take much longer to drift down if covered.
