FAQs

Dosing (14)

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.

  • Above 50° – Dose Nualgi Ponds every week as suggested by instructions
  • Between 40° & 50° – Dose Nualgi Ponds every other week.
  • Below 40° – Dose Nualgi Ponds once every month.
  • If your pond freezes – Nualgi Ponds will not be effective until above freezing.

For more tips on preparing for ponds season, please read our guide on spring opening and cleaning your pond

Bacteria become dormant in colder temperatures and the best temperature for using Nualgi with beneficial bacteria is 75-85°.

It is important to know the volume of water in your pond before dosing Nualgi. Nualgi is dosed at 1ml per 1000 gallons per week in ponds with algae. If possible, Nualgi should be dosed early in the morning. For ponds under 5000 gallons with good flow, Nualgi can be dosed directly into the skimmer or the waterfall or some other area of good flow. For larger ponds, dilute the dosage in a jar of pond water and pour it in the accessible parts of the pond by walking around the periphery.

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.

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.

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.

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.

Basics (20)

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.

Nualgi contains a special formulation of Fe, Mn, Zn, Co, Cu, Mo, B, S, Ca, Mg, P, K & Si developed for use in ponds and small bodies of water.

Upon application of Nualgi Ponds, the Nano Silica base carries 12 essential nutrients to Diatom Algae which start to multiply, consuming N and P (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.

Nualgi is a patented nano silica based nano nutrient formula in size range of 5-100 nm. The silica becomes both the carrier for other nutrients and the nutrient by itself. It contains the important micronutrient -iron (0.01% to 50% of Fe) and other micronutrients- Mn, Zn, Co, Cu, Mo, B, S, Ca, Mg, P, K. Due to its nano size, Nualgi is able to pervade very small spaces in the subsurface and remain suspended in water. This allows particles to travel farther than larger, macro-sized particles therefore providing easy absorption.

Diatoms have a silica body, unlike other algae such as Green Algae and Blue Green Algae, which have cellulose bodies. Diatoms are consumed by zooplankton and zooplankton is live food for fish. Blue Green Algae are not good for zooplankton or fish. Fewer diatoms die and decompose in the water as compared to Blue Green Algae. Excess diatoms sink to the bottom of the pond unlike other algae that form a layer on top of the water, thus cutting off light and reducing photosynthesis.

Nano refers to the metric prefix for 10^-9 and means one-billionth of something. Nanoscience is the study of structures made small enough to take on new properties. For example, nano-particles of gold appear red in color and melt at significantly lower temperatures than normal gold slabs (~300 °C as compared to 1064 °C)[1]

Nualgi has been tested in 40 degree F waters with delayed result as biological activity slows down at such temps. Ponds in cooler temps are normally clear. It’s the warmer waters that reveal problematic blooms of undesirable algae. With that said, the best temperature range to begin the use of nualgi would be 45F-50F although you could begin use at 35F.

Every pond is different and occasionally it can take some time to see noticeable changes. Possible reasons for Nualgi not working in your pond could include over feeding of livestock or dosing of other nutrients. If you don’t see a significant change in water clarity and algae control in 4-6 weeks after starting the weekly Nualgi dose, contact us to seek troubleshooting support from our expert.

Nano refers to the metric prefix for 10^-9  and means one-billionth of something. Nanoscience is the study of structures made small enough to take on new properties. For example, nano-particles of gold appear red in color and melt at significantly lower temperatures than normal gold slabs (~300 °C as compared to 1064 °C)[1].

Traditional products contain either:

  • Coarse particles with a diameter of 2,500 to 10,000 nanometers
  • Fine particles with a diameter of 100 to 2,500 nanometers.

Nualgi particles are 5 to 50 nanometers in diameter (1 millimeter = 1,000,000 nanometers).

Nano particles are known to have different properties than larger sized particles of the same element [2]. These tiny particles have a larger active surface area and can suspend themselves in liquid and are therefore more efficient by being bioavailable.

Bioavailability is a measurement of the rate and extent to which a drug or nutrient reaches the systemic circulation.  For example a drug injected intravenously is much more bioavailable as compared to a drug ingested orally.

For plants and organisms, it is a significant scientific challenge to provide nutrients in bioavailable form.  Nualgi is the only product of its kind that effectively addresses this challenge in a water body.  It’s nutrient particles are small enough to suspend themselves in the water column and are therefore more available for diatom algae to bloom.

PP and H2O2 are a quick fix for low DO levels in the water and are used to prevent fish death due to low DO (below 2mg/L at sunrise). For such emergencies, you may use PP and H2O2 while continuing to dose Nualgi after a few days of using PP and H2O2. Ponds being treated with Nualgi will generally maintain healthy DO levels thus avoiding the need for use of PP and H2O2.

Alum may be used if the nutrient levels are very high or if the N:P ratio is unfavorable to diatoms, say less than 5:1. One dose of Alum should be dosed before dosing Nualgi. If there is excess Alum that does it may bind with Nualgi. We therefore recommend a gap of few days between dosing Alum and Nualgi.
