Benefits of Using Nualgi Ponds

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 zooplankton – 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.

Customer Reviews

“I have had years of experience with garden ponds. This is my third. I am in Los Angeles, and the pond gets a lot of sun. My other ponds contained koi, but this one contains just 9 large fancy goldfish, several paradise fish, and three waterlilies. It is 1,400 gallons, has an oversize filter (suitable for a 10,000 gallon pond) and a 36 watt UV clarifier. As with my other ponds, the water is generally crystal clear, but, as before, I have had a continued battle with string algae. I learned about Nualgi in a Google search. The promised results sounded too good to be true, but I contacted the company, described my pond and asked whether the smallest, 60 ml bottle, would suffice as an experimental sample. They suggested that it should last me 40 weeks. They also suggested that I turn off my UV clarifier. When I received the bottle, barely larger than my thumb, I wondered whether I’d been duped out of $20. I also decided that I would not shut off my UV. My pond, at this point, was thick with string algae. I added the required few drops of Nualgi once a week. The algae turned brown and began dying off the first week, but I considered that this might just be a natural die-off as there had been so much. Over the first couple of weeks, there was still some new string algae, and I spent hours vacuuming up the dead clumps. The product seemed to be working, but struggling, so I reluctantly turned off the UV clarifier. It has been about 3 months now. The water is crystal clear and there is only a pleasant green patina of green covering the walls. Virtually no string algae remaining. I guess my UV clarifier is obsolete. I have never enjoyed my pond more. To say that Nualgi surpassed my expectations would be an understatement. Great product for the pond enthusiast!”  – M. Rubino   May 7, 2016
