Product Information

API Pondcare Pond-Zyme Information

API Pondcare Pond Zyme

Pond-Zyme Plus is a heavy-duty pond cleaner, containing five specially selected bacterial strains in a stable dry form. Pond-Zyme Plus breaks down fish waste and dead algae that can cause cloudy water, sludge build-up, and debris that clogs pumps and filters.

Organic matter accumulates in all garden ponds producing a build-up of sludge and causing cloudy water. The five strains of bacteria in Pond-Zyme Plus digest sludge into harmless minerals and water, visibly improving water clarity and quality.

Key Benefits:

  • Cleans and clarifies pond water.
  • Helps pond filters stay cleaner longer, reduces pond maintenance and keeps pond water clean and clear.
  • Starts working in minutes.
  • Eliminates troublesome organic sludge and debris.
  • Treats up to 30,280L

Made Specifically for: Ponds with algae problems and a build up of sludge.

Initial Dose: Using the enclosed spoon, add one spoonful of Pond-Zyme Plus for every 100 US gallons (380 L) twice a week for two weeks. Sprinkle desired dose evenly around the perimeter of the pond.

Maintenance Dose: Add one spoonful for every 760 L every two weeks.

Pond-Zyme Plus can be used in all ornamental koi ponds and water gardens. Pond-Zyme Plus is formulated to work in both cold and warm water.

We have a small pond (approx. 530L with plants & a few fishes) that we have had trouble keeping clear especially during hot summer days where the water would turn green-ish with algae seemingly overnight. We have been using a different (& pretty well-known & expensive) brand but to no avail. We found this to work very well in comparison to the other brand. We have had to couple this with the API Algaecide (as recommended by the manufacturer) when we had a very bad spell with algae, which gave us an edge. Pond-Zyme helped clear the water from dead algae after the treatment. I would have given it 5 stars if my pond water turned out crystal clear but I reckon that's a very unrealistic expectation! ;)

Bottom Line

Yes, I'd recommend this product to a friend
