5 Things to Know About Pool Algae Prevention

Vacuum once a week Weekly vacuuming removes debris that feeds algae, but it only works if your chemical levels are balanced.

Keep chlorine and pH in check Algae grows when there is food and not enough sanitizer. Low chlorine or off-balance pH will cause green water regardless of how often you vacuum.

Brush before you vacuum Brushing the walls and floor kicks up settled spores so the vacuum can remove them.

Increase frequency when needed Vacuum twice a week during hot weather, after pool parties, or when trees are dropping leaves.

Shock weekly A weekly shock treatment prevents algae more effectively than extra vacuuming sessions.
