My CYA is less than 20PPM (had about 80 last season, but now not even enough to register anything on the test).
I'm trying to clean up cloudy water to no avail, holding the chlorine at about 10PPM right now but doesn't seem to be doing the trick.

Don't want to bleach out the liner, and I know bens best guess shows between 10-12PPM for a shock value for my pool, but is it safe to go any higher?

Thanks!
