Green PondFx by Green Vista Water Gardens is a scientifically blended liquid water treatment designed to restore water quality and clarity in ponds, water gardens and other waterscapes. Green PondFx produces the same results as AlgaeFix and has a 10 percent higher concentration, which makes it more economical and efficient per application. Plants and fish, including koi, are all safe with proper application of Green PondFx.

Attenion!Please Note:

The active ingredient in Green PondFx is 100% safe for fish and plants when applied according to label directions. We have used this product safely for over 10 years at our aquatic nursery. If, however, quick acting algaecides, including Green PondFx, are applied to ponds heavily infested with algae and without proper aeration, they can lead to the stress and even loss of fish due to rapidly dying algae causing severe drops in pond oxygen levels. Green PondFx is the safest, most effective algaecide on the market for backyard ponds, but caution must be used when applying it during warm summer weather!

Application Directions

  1. Remove as much algae as possible manually before treating your pond with Green PondFx.
  2. Apply 1 teaspoon of Green PondFx to treat 60 gallons of pond water. (1 tablespoon treats 180 gallons, and 1 ounce treats 360 gallons.)
  3. Add the treatment to the area with the most circulation, such as directly by the pond's waterfall or filter.
  4. Aerate the pond heavily during the entire treatment process. Doing so is especially critical when the air or water temperature is above 80 degrees Fahrenheit.
  5. Treat the pond once every three days with Green PondFx until you achieve the desired result. Do not exceed the recommended dosage.
  6. Remove as much dead or dying algae as possible manually during the treatment process.

    This stuff is great! My 11.5k gal pond had a bunch of string algae once the weather turned to spring and was murky. After removing a 5gal bucket of algae I poured a 32oz bottle of FX into my waterfalls charge basin and 3 days later my pond is clear and I went swimming:)

    We have used PondFX algaecide for several years. Each spring, we get a bloom of string algae that turns our goldfish pond into a green mess. After dosing the pond with the PondFX once or twice, the algae is killed off and gone! We have tried other products but PondFX absolutely works the best of them all! Highly recommended.
