How Does Nualgi Ponds Work?

Within 3 – 5 hours of applying Nualgi Ponds, a bloom of Diatom algae (the good kind!) will develop. The diatom algae bloom out-compete nuisance algae for CO2, N, P and other nutrients, causing the bad algae to die off. It then locks away some of the harmful nutrients in the new bio mass that is consumed as live food for your fish and zooplankton. The growth of diatoms provides oxygen to bacteria who in turn clean up the waste products of fish and leftovers. The exponential growth of diatoms provides oxygen to bacteria who in turn clean up the waste products of fish and leftovers. This natural process helps clean ponds and make their water sparkling while helping reduce bad odors.

What Are the Benefits of Using Nualgi Ponds?

  • NATURAL ALGAE CONTROL FOR PONDS, WATER GARDENS & FOUNTAINS – Control algae growth and clear green water – without toxic algaecides or expensive UVs!
  • IMPROVE WATER QUALITY & CLARITY – Safely restore missing nutrients & balance your pond’s chemistry for improved water quality and crystal clear water!
  • ELIMINATE OFFENSIVE POND ODORS – Supercharge your pond’s Nitrogen Cycle and puts beneficial bacteria to work cleaning up waste & pond sludge.
  • PROMOTE THE GROWTH OF DIATOMS & ZOOPLANKTON – The diatoms fueled by Nualgi are quickly hunted down and eaten by zooplankton – the preferred live food for your fish!
  • ENHANCE FISH HEALTH, COLOR, AND ACTIVITY – Koi pond owners will see their fish be more active chasing down their free food while health & color improve from a more balanced diet and overall ecosystem.
  • IMPROVE AQUATIC PLANT HEALTH & GROWTH – Water gardeners will see all their aquatic pond plants flourish once your water chemistry is balanced and missing nutrients restored.
  • INCREASE DISSOLVED OXYGEN LEVELS – For many eutrophic ponds, results may be visible by afternoon on the first dose – starting with the bubbling up of oxygen you can see!

    Dose 4 this morning. Doing the 10 % water change on Friday mornings then dose Saturday early morning. Still no change in the beautiful bright green water, I do nit nor have I had string algae just this hard to get rid if single cell… In going to continue treatments in hopes that it will clear my water, I miss seeing my fishies

      Stay patient Donelle :). You could dose every 5 days instead of 7. In problem ponds, you could also dose Microbe-lift PBL twice per week according to their instructions. Once improvements start you can go back to regular dosing of Nualgi. Stay in touch, we’d like to you to see your fish too!

    I tried this last year in my 3300 gallon pond. Did not have a great result. I had to use an algaecide to remove the string algae. It was pretty much an ongoing battle. This year I made some changes and cleaned grass etc. away from the edge of the pond. I vacuumed and manually skimmed the pond. I also flush the pond out a little every week. I started using the product about 1 month ago and I am pretty impressed with the results. Not one bit of algae so far and it has been very hot. I have a lot of lichen on my rocks and that is being reduced as well. I did notice when ever I dosed the pond it seemed to put the fishies in the “mood”. There was an awful lot of spawning going on. A koinkydink maybe, but awesome product. My fish are far more active then they have ever been and my water is getting clearer all over he time. And my pond does not smell like a static tank. Thanks Nualgi. I wish Canadian stores would carry this.

      Thanks Dar. When you improve oxygen levels in the pond the fish can get in the “mood”! When animals feel secure, they spawn. We have many users tell us about spawning when using Nualgi. In aquaculture ponds, we have seen numbers grow from 50k fish to over 100k on maturity. There are stores in Canada carrying it. Please contact neil@prosourcesupply.ca for list of vendors near you

    Worked wonders! Have a 500 gallon pond with everything covered in a dark algae slime. Used the tiny amount as directed and all the slime just disappeared totally within three weeks and the koi and goldfish were unaffected and happy! Definitely use as directed. A very little goes a long way.

    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.

    It took a month to see results. Which was stated as a possibility. During that time I did a lot of manual removal of the string algae. I probably scooped 5 pounds out of my pond. I’m not sure this would have been effective without doing that. At this point even the surface of my rocks are starting to clean up. So I’d say it works. I’m wondering if a little string algae may be good for the fish going into winter so today was my last treatment for 2017.I stopped using over the winter and the string algae exploded again. I started manually removing and using this again on my 1000 gallon pond this spring. Took another month, but once again it cleared the string algae out. I’d say manual removal is a must on the big strings

    This stuff actually works. Not sure how, but I ,put in 2 mils for a week until algae was under control and now I use 1 mil per week for maintenance. The water is a lot clearer.
