Before Nualgi Ponds…

Green pond BEFORE using Nualgi Ponds

“We moved into our new house with an existing pond and it’s been three years of living hell trying to maintain the pond. This Spring, water was so green you couldn’t see 2 inches beyond the surface.”

After trying Nualgi Ponds

Clear pond AFTER using Nualgi Ponds

“It works great. Couldn’t be happier with this product. Water is super clear now and I fully enjoy my pond…I haven’t used the UV light since I unplugged it this Spring. I used a $25 bottle of Nualgi and it lasted me all summer. So much cheaper than a $100 UV bulb and does a better job!“.


  1. I have been using your treatment for 2 years now and I am very happy with the results. Our oldest pond is 15 yrs old. Suddenly this year when it rains the pond gets very muddy and the filters require constant cleaning. This has never happened before. Is there something that I can do or is this just Mother Nature? My new pond does not do this. I haven’t made any changes to the pond or surroundings.

    • Frank, it is always a puzzling to find adjoining ponds behave so differently. Our suggestion is to get expert help using

  2. Have a small backyard pond of approx 130 gallons. Have been using a UV sterilizer for many years. While it keeps the water very clear, it does not affect the string algae. So, once or twice a season, I have to empty the pond and remove it manually. I have tried a few algae control products with minimal success. So, I came across Nualgi and thought it was worth a try. Well, after only about 5 days, all of the string algae is gone and the water is sparkling clear. This stuff works.

    • Thanks for the feedback Ron! So glad you and your pond are seeing the benefits of Nualgi.

  3. I have tried everything in my pond water still like pea soup

  4. I don’t understand why this doesn’t work on my pond…..each year I try it …
