Microbe-Lift Algaway 5.4 Algaecide

Compare to AlgaeFix, same active ingredient and 20% more concentrated.

Algaecide For Ponds - Stops Algae Growth & Controls string algae!

No more green water with ALGAWAY 5.4 Algaecide!

It stops algae growth in ponds and can be applied to areas that contain fish and plants!

For use in self-contained ornamental ponds and fountains without any outflow. For small ponds with heavy algae growth, clean the excess algae off the sides and ornaments before adding ALGAWAY 5.4 . This will reduce the amount of decaying organic matter.

Fountains, Small Ponds with goldfish and koi - Treat only those fountains and ponds which will have no outflow after treatment. High water temperatures cause more rapid natural decay of dead algae which can cause fish distress. If animals are present clean out excess algae as stated above or use before temperature exceeds 75°F (24°C).

CAUTIONS: In ponds, insure that water is well aerated via waterfall, fountain or other method to prevent fish loss. Aeration must be continuous. Not safe for use with snails, shrimp and other crustaceans or mollusks.

Repeat dosage once per week.

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
