What is Mustard Algae?

  1. Mustard algae, a type of chlorine-resistant green algae, can often be mistaken for dirt or sand in your pool and is resistant to regular cleaning methods.
  2. Effective treatment of mustard algae involves a series of steps including regular pool brushing, vacuuming to waste, and a consistent routine of shock treatments and algaecide applications.
  3. Consistent monitoring and maintenance of pH, alkalinity, and sanitiser levels are crucial in preventing a Mustard Algae resurgence in your pool.

How to remove Mustard Algae from your pool

Mustard algae is a type of chlorine-resistant green algae that often clings to the pool's sides and bottom, often mistaken for sand or dirt. It's known for its stubbornness, as it quickly reappears even after being easily brushed away.

This persistent algae can often create an illusion of a malfunctioning pool cleaner, as pool owners may find that their pool cleaner fails to pick up this "dirt". However, the truth is that Mustard Algae can't be successfully eliminated by ordinary pool cleaning methods.

Unlike standard dirt and debris, Mustard Algae is immune to regular pool cleaners and filters. As it is a living organism, it easily bypasses the cleaning process, only to make its unwelcome return to your pool.

For successful removal of Mustard Algae, specific chemical treatment is necessary. By following a series of steps, you can ensure a Mustard Algae-free pool.

Firstly, regular pool brushing is crucial in the fight against Mustard Algae. Keeping the algae in suspension aids in its effective eradication.

Additionally, filling your pool to the brim before vacuuming to waste is recommended, as Mustard Algae can reside within your pool filter.

Shock treatment is another effective method in this process. Triple shock your pool, and support this treatment with a high-quality algaecide for optimal results.

To maintain an algae-free pool, weekly shock treatment during the summer months is advised, ideally in the evening. Follow this up with another round of pool brushing.

Lastly, maintaining the correct pH, alkalinity, and sanitiser levels at all times can prevent a Mustard Algae comeback.

Adhere to these guidelines to enjoy a clean, Mustard Algae-free pool throughout the year.
