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.
