Yellow Treat®2: The Trusted Solution for Stubborn Algae Blooms

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.

    verry good

  2. Keith Feather

    Like the product. Impressed by the way UC stood up to the ridiculous claims by competitors. I do wonder what the other additive, chlorine boost, is, since it is listed as not an active material. I was supposing BCDMH, but that would be listed. Seems to work, but would like more knowledge about this addition to the Yellow Treat.

    • Scott Hamilton (verified owner)

      Thanks Keith. While the chlorine boost is a secret, I can tell you that it acts as a chlorine stabilizer / hypochlorite scavenger. It is not, however, cyanuric acid. Also, “active” and “inactive” are a bit misleading, as it implies the rest doesn’t doing anything. That’s a bit of a limitation of current EPA labeling requirements. It’s more appropriate for single ingredient products (which this is not).

  3. Mark Lodwick

    Scott, in your response to Keith on June 3, you mention “hypochlorite scavenger”. That sounds counterintuitive for those of us in the pool service industry. Can you elaborate? Thanks

    • Scott Hamilton (verified owner)

      Hi Mark, great question. A hypochlorite “scavenger” is a compound that simplifies and removes certain oxidation reactions involving hypochlorites and specific organic compounds. A less technical but more direct explanation is that the additional ingredients stabilize hypochlorite. The reaction is somewhat similar to how CYA works, but without the same UV protection – so it won’t necessarily replace CYA. It does however make the hypochlorite and algaecide overall more effective. Hopefully that makes it a little clearer. Cheers

  4. Jan D Dye

    Quality products and phenomenal help to conquer pool issues.

  5. Dennis

    Will this product add to my CYA level? I’m up around 90 and don’t want that to go up anymore.

    • Scott Hamilton (verified owner)

      No. Yellow Treat contains zero Cyanuric Acid (CYA).
