Brush & Remove Debris

To prevent algae growth, brush your pool weekly to remove any spores that have attached to the walls or steps. Trees and plants are a common source of algae spores, so trim leaves and branches back as much as possible and remove leaves and other debris from your pool right away.

Add Chemicals

Shock your pool weekly to boost chlorine levels and keep your water crystal clear. Using an HTH® shock treatment is one of the best ways to protect your pool from algae. For best results, use an algaecide like HTH® Super Algae Guard 12 to 16 hours after the shock treatment to further prevent future algae growth.
