4 Steps to Fix a Green Pool

Shock the water Use calcium hypochlorite or a non-stabilized shock to kill the algae. Follow the dose on the bag exactly.

Run the pump and brush Keep the pump running 24/7. Brush the walls and floor to break up algae clinging to surfaces.

Vacuum to waste If your filter has a waste setting, use it to send dead algae straight out instead of back through the filter.

Add clarifier if needed If the water stays cloudy the next day, add a clarifier to clump dead particles so the filter can catch them.
