Green-to-clean

A green pool is algae, and algae grows when the chlorine runs out: a heat wave, a storm full of leaves, a pump that stopped. It looks hopeless and almost never is.

On the first day we skim and net the worst of it out, brush every surface and dose a heavy shock with algaecide. Then we come back every day to brush, clean the filter and test, until you can see the drain and the readings hold. We almost never drain a pool to do it.
