Why it happened
Low chlorine is the cause almost every time: a missed week, a storm that diluted the water, a pump that stopped, or stabilizer so high that chlorine stops working well.
The first steps
Keep the pump running around the clock. Test pH and bring it into range so the shock works, then add enough chlorine for the volume and brush every surface.
Clean the filter as the algae dies off. A loaded filter is why a pool turns from green to cloudy and stays that way.
When to call us
If the water is dark green, the filter is struggling, or you need it clear for a showing or a party, we can take it from here.
