An innovative approach to improving pond balance, Nualgi Ponds™ is built on a nano silica base with our patented formula of 12 essential elements that safely help restore the natural balance, improve water quality and control nuisance algae.

Engineered specifically to benefit the health of your aquatic plants and fish, Nualgi Ponds™ is easy to use, efficient, and yields rapid results.


I ml of Nualgi is applied to 1000 gallons of water once a week.

Shake the bottle well before dosing.

NUP04 - 125ml/4oz

NUP08 - 250ml/8oz 

NUP16 - 500ml/16oz


Nualgi is a liquid mixture which is diluted in water dosed into ponds once a week. It is effective within hours of dosing.

What is Nualgi?

Nualgi contains nano-scale micronutrients (5-100nm) required for multiplication of the ubiquitous and beneficial diatoms in any water body. Nualgi contains Si, Fe, Mn, Ca, Mg, Zn, Cu, B, S, Mo, P,K and Co

How does it work?

Nualgi causes a controlled and sustainable growth of beneficial diatoms. Diatoms are unicellular microscopic aquatic plants that absorb carbon dioxide and release oxygen during photosynthesis.

Higher oxygen levels in water enable aerobic bacteria to grow and breakdown the organics in the water.

Higher DO level also results in tangible changes like cleaner water, reduction in BOD, lower coliform levels, elimination of foul odor, reduction in mosquito colonies in water and healthier aquatic life. Nualgi eliminates the use of UV filters thus saving costs. It is also a substitute for algae control products and water clarifiers.

Why Diatom Algae?

Diatoms have a silica body, unlike other algae such as Green Algae and Blue Green Algae which have cellulose bodies. Silica shells photo- synthesize faster and earlier in the day due to their silica (translucent) frustules and therefore outcompete other algae like the harmful Blue Green algae (BGA). Highly mobile, Zooplankton feed on the diatoms which trigger growth in their numbers. Zooplankton is the best live food for fish and feeding on them, they become healthier and heavier with higher protein level. The organics exit the water in the form of fish biomass.

What are the specific changes that Nualgi causes in water? 1 liter of Nualgi:

  • Releases 100 to 500 kgs of Oxygen depending on the condition of the water.
  • Produces 100 to 500 kgs of Diatoms
  • Consumes 8 to 40 kgs of N and 1 to 6 kgs of P
  • -Consumes 150 to 700 kgs of Co2


Application Process:

Nualgi mixes very easily in water, mechanical mixing is not required. Nualgi is dosed directly into the filter or skimmer early in the morning once a week.


Nualgi has been tested to be non-toxic as per APHA (2012) and OECD (1992)


Nualgi has no impact on humans and is even safe if small amounts are consumed accidentally. Overdosing will cause excess diatoms and water will turn brown.

Side Effects:

Nualgi has no side effects when dosed in water. Beneficial bacteria, zooplankton and fish grow in a healthy manner in ponds and lakes dosed with Nualgi.


Gallons In Pond     Max Amount

    100                        0.1 ml

    500                        0.5 ml

  1,000                          1 ml

  5,000                          5 ml

10,000                       10 ml

Adding extra will actually reduce the effectiveness. It is better to do half a dose than to overdose.


You should see less algae buildup on the pond surface and in the filter. Eventually you’ll be able to reduce the amount you feed fish. If you have floating plants, you should see them thrive and become more colorful. In all ponds water should look clearer with fish more active & vibrant.

Patience is important with Nualgi. Some ponds clear in a few days, while others can take over 4 weeks. If it has been over a month of dosing and you have not achieved results, please contact us to help troubleshoot.

In a severely eutrophic ponds, results will be visible by the first afternoon – bubbling up of oxygen, foul odor stops, Blue Green Algae may crash and float up, etc. Water may appear brown or turn green, but that is part of the biological process.


Shake the bottle vigorously and measure out the proper dose. Better to under dose than to add more than the recommended amount.

 Physically remove dead leaves, debris and any algae that you can scoop out before starting the Nualgi dose.


Nualgi Ponds should be dosed every 7 days, preferably in the morning to maximize effectiveness.

You can use Nualgi Ponds throughout the winter 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.

40°-49° – Dose once a month

50°-59° – Dose once every two weeks

60°+ – Dose once a week with normal instructions
