How To Get Rid Of Yellow Algae In Pool

Mustard algae, which are greenish-yellow or brown, often cling to pool walls and other items including pool equipment, toys, and even bathing suits. It is most commonly found in regions with warmer climates, but mustard algae can grow in all pools. Because it is chlorine resistant, mustard algae can be difficult to remove once it’s in your pool. Mustard algae will stick to the walls or bottom of the lake, not floating like green algae. It can also be found in hidden, shady areas such as steps, around lights, and in pool filters.

How to Get Rid of Mustard Algae Even if you take all of the precautions above, your pool can still be contaminated with mustard algae. Once you have mustard algae, don’t take it lightly. Here are nine steps to solving this difficult problem.

Remove all items from the pool, except cleaning tools, that you will disinfect when you shock the pool. Wash pool toys and other items with chlorine or chloride based cleaners. Wash your swimwear.

Brush the algae and then let it settle. Vacuum with exhaust mode.

Balance your pH and alkalinity. Your pH level should be between 7.2 and 7.4 and your alkalinity should be between 60 and 120 ppm. Balanced water will help the shock work faster.

Shock your pool with chlorine – twice the amount you would use for a typical shock treatment. Brush the algae vigorously, this will help the vibration destroy algae from the small crevices in the pool surface.

Run the pump and filter 24 hours a day until the algae are gone.

Backwash/clean filter media and inspect your pool. If it doesn’t improve, shock again.

Vacuum up the waste in your pool to get rid of any leftover algae so it doesn’t start growing again.

Water treatment with algaecide.
