Biosafe GreenClean Granular Algaecide For Rapid Algae Control

Through the power of oxidation, GreenClean Granular Algaecide breaks down algae cells on contact!

Its unique, organic chemistry immediately begins fighting algae blooms and releasing vital oxygen into the water as it biodegrades. This solution can be used as a curative or preventative treatment in any water feature. Formulated without the use of harsh chemicals or chlorine, you will be worry free because nothing negative can effect your aquatic ecosystem. Trust GreenClean to immediately kill algae in any water feature around your home including ponds containing fish, plants, and aquatic life. GreenClean is an EPA registered, organic algaecide, so you can feel good about what is in your water.

  • Controls string algae in ponds, waterfalls, streams, and rocks
  • Safe for use around pets, birds, fish, and aquatic plants
  • Copper alternative
  • Works on contact
How Does GreenClean Granular Work? GreenClean is a granular algaecide with an activated peroxygen chemistry that works through a powerful oxidation reaction to break down algae cells on contact. An added benefit, the process releases oxygen into the water as it works to eliminate algae.

I Have Fish In My Pond: Can I Use GreenClean? GreenClean will not harm fish or aquatic life. GreenClean once diluted in water is non-harmful to animals such as birds, bees, and pets.

Can I Use GreenClean On My Waterfall? Yes, as a contact algaecide the granules need to make contact with the algae to be effective. Our recommendation for treating waterfalls is to turn the pumps off, apply GreenClean directly to the algae, and then turn them back on after 20 minutes.

Will GreenClean Affect The pH Level? GreenClean will raise the pH up to 1 unit. Although this will comeback down on its own within about a week. Test pH prior to using and apply in the morning. 

Note: This Product is Toxic to Birds in Raw Form

  1. Apply early in the morning under sunny, calm conditions.
  2. Measure the pH of water before treatment. If pH is below 7.0, adjust the water pH to between 7.0 and 8.0.
  3. Distribute recommended dose as evenly as possible to several areas around the pond so product evenly disperses. It may also be mixed in a bucket of pond water and evenly distributed around the pond.
  4. Do not shut off pump(s) or aeration device(s); aeration must be continuous during treatment for 48 hours.
  5. Repeat dose every 3 days until algae is under control.

Removing excessive algae growth will reduce the amount of decaying organic matter in the pond.
