Nualgi Ponds 125ml Bottle


Nualgi is a highly concentrated liquid selection of micro-nutrients on a nano silica base that feed diatom algae. Diatom algae are a silica based naturally occuriung algae that use the nutrients in a pond or lake so that cellulose based green and blue-green algae cannot thrive. Diatoms are clear and not visible and are consumed by zooplankton and zooplankton is food for fish. Nualgi works well in combination with beneficical bacteria such as Microbe-Lift PL.

Dosage:Nualgi Before and After

1ml per 1000 gallons diluted in 100ml of water applied once a week

  • 60ml (Treats 60,000 gal)
  • 125ml (Treats 125,000 gal)
  • 250ml (Treats 250,000 gal)
  • 500ml (Treats 500,000 gal)
  • 1L (Treats 2,000,000 gal)

Important Note:

Nualgi cannot be used with UV lights, Ionizers or algaecides as they kill the diatom algae.

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 thefirst 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.

What is Nualgi Ponds?

Nualgi is a liquid additive containing 12 essential nutrients on a nano silica base to restore balance, improve water quality, and control nuisance algae in your pond. Nano silica is both a nutrient and a carrier that prevents the nutrients from reacting with each other.

Unlike traditional additives, Nualgi’s nano scale (measuring 5-100 nm) nutrients remain suspended for longer duration, disperse easily across the water column and are therefore “bio-available” to marine organisms.

How Does Nualgi Ponds Work?

Upon application of Nualgi Ponds, the Nano Silica base carries 12 essential nutrients to Diatom Algae which start to multiply, consuming Nitrogen and Phosphorous (from left over fish food and fish waste) and robbing the nuisance algae of these nutrients. Due to the silica shell the Diatoms photo-synthesize earlier in the day as compared to nuisance algae. Diatoms release O2 & consume CO2, thus increasing the dissolved oxygen levels. Higher DO levels help aerobic bacteria break down organic matter. Diatoms also happen to be the favorite food for Zooplankton and as they grow, Zooplankton population also grows exponentially in the pond. Finally, Zooplankton, a live food for marine life gets consumed by fish, thus completing the food chain.


Frequently Asked Questions


When Should I Start Seeing the Effects of Using Nualgi Ponds?
For particularly bad cases of algae, results might be visible within hours and the pond may appear to get worse before it gets better in extreme cases. Take a deep breath, a few pictures for reference, and if you still don’t notice the effects at least a week later please contact us.
How Do I Dose Nualgi Ponds in the Spring and Fall?
You can use Nualgi Ponds throughout the fall and spring by following dosing on the label. Use reduced dose frequency as the water temperature changes. Below is a guide on how often to apply Nualgi Ponds into your water system.
  • 5°C - 10°C – Dose once a month
  • 10°C - 15°C – Dose once every two weeks
  • 15°C + – Dose once a week as suggested by instructions
Is Nualgi Ponds Safe for Koi and Other Fish?
Yes. Nualgi is made with all fish in mind. From Koi to Trout, Nualgi Ponds is beneficial to all aspects of your water garden. This includes amphibians, invertebrates, bivalves and crustaceans.
What is the Dosing Process and How Long Does it Take?
Physically remove dead leaves, debris and any algae that you can scoop out before starting the Nualgi dose. Extract the appropriate dose and dilute it 10 times in water. Pour the mixture directly into your pond while walking around the periphery. Diatoms are most active immediately after sunrise. Therefore dosing Nualgi in the morning is recommended.
Can Nualgi Ponds Be Used on other Plant Life Around my Water Garden?
Nualgi Ponds enhances the color and growth of your water garden due to enhanced water quality and availability of micro nutrients.
Is Nualgi Ponds Safe for Use Around Animals, Pets, and Children?
Yes. Nualgi is a natural product with no harmful chemicals like algaecides. It is safe for dogs, amphibians, birds, plants and all other inhabitants around your Koi pond and water garden. Nualgi is non-toxic and not harmful if ingested. If you or a child did consume the formula and is having any issues, please consult your primary physician. If it gets in your eyes, rinse and wash with water immediately.
Is Nualgi Ponds Toxic?
No. Nualgi is made with Nano Silica which is amorphous silica of 100 nano meters or smaller. Crystalline silica of 1 micron (1000 nano meters) or more may be carcinogenic.





I Am Using Nualgi and Beneficial Bacteria but my Water Continues to Remain Green?
Nitrate, nitrite and phosphate levels may be high. If not then bacteria being added is not sufficient and must be increased. Please contact us through our troubleshooting form for more assistance.
My Pond Had Cleared up with Nualgi but my Water Has Now Turned Green Again?
You may increase the Nualgi dose by half for 2 weeks. If conditions improve, dial back to recommended dose. Sometimes ponds need a little more or a little less than the recommended dose.
I Added Nualgi and Now I Have Foam on my Pond?
Foam is the result of algae dying off. Manually remove it with a fine mesh net so that it will not fall back to the water column. Also, be sure to keep filter clear and flowing properly. Algae cells build up quickly in the filter.
I Have Pond Plants in my Water Garden. Won’t the Diatoms Out Compete Both the Algae and my Plants?
Diatoms will out compete both algae and plants. However the sequence is that first other single celled algae are starved out and only later plants stop growing. The impact on plants depends on the dosage. Recommended Nualgi dose of 1ml per 1000 gallons per week ensures that only the algae is impacted and not the plants. If any impact is seen on the plants then the Nualgi dosage can be reduced.
My Water Turned Brown After Using Nualgi?
There are two possible reasons for your water to turn brown while using Nualgi. An overdose of the product will create a diatom over bloom this will discolor the water to a light brown. The other possible browning of water would be due to algae cell die off and either poor filtration or filtration being purged and cleaned. To determine which is which, take water from a minimum 12″ depth into a clear glass. Allow the glass to sit for several hours then look to the bottom of the glass. If it is littered with debris it is a filtration issue if it is not littered with the debris it is a diatom over bloom to which you will reduce the use of Nualgi.
Water Column is Clear but Cannot Get Rid of String Algae?
String algae can be addressed with a combination of Nualgi and Beneficial Bacteria. It can take up to 16 weeks for string algae to die out.
Can higher chlorine/chloramine levels in my source water (municipal or well) affect water clarity? What should I do?
Yes, it impedes the nitrification process in the pond, thereby slowing down the effect of Nualgi and Bacteria that you may be dosing. If you have been treating the pond with Nualgi and beneficial bacteria, and yet find that the water is not getting clearer, one reason may be higher chlorine/chloramine levels. In such cases please treat your pond with an efficient dechlorinator (recommend Novaqua) . In cases where it has just rained, dosing dechlorinator in the pond may be prudent. The dose should be as recommended by the manufacturer.
