Your Pool Sat Cold All Winter.
Algae Didn't.

It's August. While you weren't looking, algae spores settled in, phosphates built up, and that water under your cover has been quietly turning green. One dose now stops it before spring arrives in weeks.

Open your cover to a surprise? Make it a clear one.
