At the risk of sounding stupid...

I bought a solar cover for my pool which is basically a giant bubble-wrap sheet of course , It has been on my pool for a couple of days-and I'm noticing that when I test my fc levels they levels are much higher than they had been before I started using it so my question is does it block enough Sun that it's protecting my chlorine better ?

Yes.

And it's also normal to see some CC immediately after pulling the cover off, since it hasn't had sunlight on it to break it all the way down.

Huh, never even thought of that honestly, I knew the cover would heat water, never dawned on me that it would block uv rays that much...guess I better cut my runtime on my sag as long as I am using it during the day
