Win the Battle Against Mustard Algae

When you see that yellowish “dust” on your pool steps or walls that just won’t brush away, you need a solution that delivers results . Yellow Treat®2 is the legendary algaecide formula from United Chemical, specifically engineered to defeat the toughest mustard and yellow algae blooms that standard chlorine alone cannot handle.

Mustard algae is highly resistant to sanitation. Yellow Treat® 2 works by penetrating the protective coating of the algae, allowing your sanitizer to destroy it from the inside out.

  • Universal Application: Whether you have a salt system or traditional chlorine, this product is the helpful partner you need to get back to swimming.

Directions for Use

  1. Measure & Apply: Add 5 ounces (one level capful) of Yellow Treat®2 for every 10,000 gallons of pool water. Broadcast the granules directly onto the surface of the pool water.
  2. Brush Thoroughly: Immediately brush the pool surfaces, focusing specifically on areas with visible algae growth to expose the blooms to the treatment.
  3. Shock: Immediately following application (regardless of your current chlorine reading), add liquid or dry chlorine to “shock” or super-chlorinate the pool. Follow the super-chlorination dosage rates listed on your specific shock product.
