Mustard Algae

Overview

Troubleshooting & Treating Mustard Algae

Mustard algae have a yellow, powdery appearance and tend to thrive in the shady part of the pool - an appropriate spot for scum to hang out.  Like Black Spot algae, they have protective layers and are therefore more resistant to chlorine.

  1. Check the pH level of the pool to make sure it's between 7.2 and 7.6, then boost the chlorine levels using Pool Ezy Purifier.
  2. Turn the pump off to stop water flow to ensure more accurate targeting.
  3. Brush the affected areas vigorously to remove the protective coating of the algae.  Add All In One Pool Algaecide directly on top of the affected area and leave overnight.
  4. If your pool is cloudy, it means that there are lots of suspended dead algae cells in the pool.  Use Power Clarifier Liquid or EZY Clarifier to send them straight to the pool's floor. (Refer to Murk and Cloudy Water treatment guide).
  5. Vacuum those pesky particles to waste, then use EZY Natural Clarifier to bring the sparkle back.

For an additional preventative measure, add Phosphate Remover and EZY Natural Clarifier.

NOTE: All cleaning equipment should remain in the pool when treating to prevent reinfestation.
