When you supplement your regular maintenance with Nualgi Ponds, you will be able to:

  • WATCH YOUR POND FLOURISH – Nualgi Ponds will significantly improve water quality as well as the health of fish and plants. For many eutrophic ponds, results may be visible by afternoon on the first dose– starting with the bubbling up of oxygen, elimination of odor, and Blue Green Algae crashing and floating to the surface.
  • SEE MORE – By reducing nuisance algae growth, Nualgi Ponds improves water clarity and visibility to reveal more of the pond’s environment and its inhabitants.
  • FEED LESS – By restoring missing nutrients, Nualgi Ponds brings balance to the natural marine food chain from the bottom up by promoting the growth of diatoms and zooplakton – free food for your fish and shrimp!
  • SHOW IT OFF – Enjoy peace of mind knowing that your pond is healthy, clear, and odor-free.  Friends and guests will be impressed, and we won’t tell them how easy it was to restore the natural beauty of your pond.

    We used this in conjunction with beneficial bacteria and our formerly pea soup pond is now clear after about 2.5 weeks of use.

    I tried using this as directed and it did nothing for the 200 gallon tank I had. So I tried doubling the dosage and still had no affect.

    initially worked to help with string algae. But over the year, it didn’t work as advertised in controlling algae. finally had to drain and clean the pond. After we refilled and added this product, the algae came back

    Hello,Nualgi Ponds is a fantastic product! We have a 4500 gallon koi pond and algae began forming in late fall 2017. We applied the product and within two weeks and the algae was completely gone. The water is now crystal clear. Amazing! Will buy again.Thank you!EBS

    Best product for algae control. The brown after effect is easily removed with a hose. I’ve tried everything else; this is great. Fish don’t seem to be affected by it.

    I would recommend this product. It cleared up my pond nicely.

    I noticed one thing that most reviewers don’t make clear is what type of algae they were trying to control, whether string algae or the single-cell variety that makes your water look like pea soup. From my experience this product worked very well to eliminate string algae but was absolutely worthless for controlling single-cell (green water) algae. So if you’re trying to control string algae, this product is likely to work very well. However, if you’re trying to control the single-cell (green water) variety, don’t waste your money on this product.
