My go-to for keeping the pool crystal clear. Doesn’t raise CYA and packs a solid dose of calcium hypochlorite for an effective shock every time.

I sprinkle this in our pool weekly as part of my maintenance routine. I e just now begun to notice that it bleaches my liner making the bottom rim super light. Now that I know that I sprinkle all throughout the pool and disperse more evenly. This product makes the pool smell super clean and keeps the water extra clear. Although it bleaches my liner, I highly recommend.
