Recovering a Green Pool in Miami: General Guidance

First, brush the entire pool — algae bonds to Miami's plaster surfaces quickly, especially on older interiors, and shocking without brushing may waste chemicals.

Adjust pH to about 7.2, then shock with cal-hypo or liquid chlorine at a heavier dose per label directions. Run the pump continuously and clean the filter as pressure rises. In Miami's heat you may need to shock twice.

A quality algaecide can help after shocking. Persistent green often means the filter isn't up to the job — Miami's warm water lets algae rebound overnight, so consider professional help if it comes back.
