FC: 3
pH: 7.5
CYA: 30
CH: 275
TA: 90
I have a solar cover on my plaster pool and am wondering how quickly I can put the cover back on after adding Cal Hypo for chlorination. I usually add enough to raise FC by 2.5. Leslies store told me it should be 80% dissolved before it even hits the bottom. But after a few minutes, I see sparse patches of precipitate floating on the water. I was wondering if that precipitate is chemically active, or is it just leftover calcium or carbonate that I can toss the cover back over without harm.
Used to use liquid chlorine, but it's become quite expensive compared to CalHypo when it's on sale, and doesn't tend to leak in my car. Also, I have a small pool leak, so CH keeps dropping over time.
