How to Prevent Algae Growth in Swimming Pools
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.
Clean Your Filter
Your filter effectively removes dead algae spores from your pool. Use HTH Filter Cleaner to clean all filter types and help the filtration system to work more efficiently.
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.
Frequently Asked Questions
What is pool algae?
Algae are microscopic forms of plant life that can inhabit your pool water. Green, black and yellow algae are three common types that can float in the water or cling to the sides of your pool. Algae spores are constantly blown into the pool by wind and rain. If you don’t take steps to prevent algae, your pool water can become cloudy, discolored and even slimy and smelly.
How does an algaecide work?
Algaecide causes the cells of the algae to burst, destroying the plant. Then, the pool filter removes the dead algae cells from the water. Different algaecides are used for different types of algae. For example, HTH Algae Guard10 is more effective against green algae. HTH Super Algae Guard can be used for green, black or yellow algae.
When do I use an algaecide?
If your swimming pool has an algae problem, brush the floor and sides of the pool, balance the water and use a shock treatment. Then, add the algaecide to the water. Algaecides can kill algae spores in your pool, but they are even more effective at prevention. Use an algaecide once a week 12 to 16 hours after each shock treatment to protect your pool and keep your water crystal clear.
