Mustard algae

You’re dealing with mustard algae in your pool because poor circulation, inadequate filtration, and imbalanced water chemistry have created perfect conditions for it to thrive.

This algae loves shady, warm spots and resists normal chlorine levels, making it stubborn to remove.

If your pH and sanitizer aren’t right, or you skip regular brushing and cleaning, mustard algae will quickly take hold. Keep going, and you’ll find out how to fight it effectively.
