Remove Debris

After heavy rain, you should clean and treat your pool to remove debris, rebalance the water chemistry, and prevent algae growth: 

Use a skimmer net or leaf rake to remove large debris, and a roller vacuum to remove smaller debris. Pay special attention to the pool’s water line and step-outs. 

Test and rebalance water chemistry

Rainwater can introduce pollutants like dirt, bacteria, and pollen, which can affect the water’s chemistry. You should monitor the pH and alkalinity levels. 

Add chlorine

Chlorine is a common pool sanitizer that kills bacteria and other harmful microorganisms. You can add chlorine in the form of tablets, granules, or liquid. 

Use an algaecide

If algae have grown, you can use an algaecide to brush it off the pool’s surface, walls, steps, and floor. 

Use a phosphate remover

If your pool has a lot of soil or mulch, you can use a phosphate remover. 

Drain excess water

If the water level is too high, you can use your pool pump set to “waste” or “backwash” to drain it

Maintain proper filtration

A good filtration system can trap debris and algae.
