Use Pool Protector to prevent algae from growing in your pool. An algaecide should be used regularly, and especially when you shock your pool. Always shock your pool first and allow the chlorine levels to come back to normal before adding algaecide.

Always read the instructions carefully, and add the correct amount of algaecide to different places around the pool while the pump is running.
