Nualgi Ponds - Naturally Balance Your Pond

Eliminate Nuisance Algae & Get Crystal Clear Water – Without an Algaecide!

Nualgi is Safe for Fish, Plants, Amphibians, Birds & Pets!

We regularly use Nualgi here at Hydrosphere with great results!

Safely improve water quality and balance the nitrogen cycle in your pond to reduce maintenance, bad odors, and fish feed by treating with Nualgi Ponds. Our breakthrough formula adds missing nutrients back into the water for healthier plants and fish.

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.

Nualgi Pond ComponentsWHAT 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.

Nualgi Ponds DiatomsHOW DOES IT WORK?

Within 3 – 5 hours of applying Nualgi Ponds, a bloom of Diatom algae (the good kind!) will develop. The diatom algae bloom out-competes 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.



Nualgi Pond BenefitsWHAT ARE THE BENEFITS?

Nualgi Ponds has been developed specifically to starve nuisance algae, reduce foul odors, and increase oxygen levels in your pond. Nualgi promotes greater fish and plant health while keeping the water crystal clear. Enjoy your new habitat and show off your pond as your fish become more active and your plants gain more color.



Directions For Use:

Nualgi is dosed at 1ml per 1000 gallons per week in ponds with algae. If possible, Nualgi should be dosed early in the morning.

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

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.

What To Expect
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. In a severely eutrophic ponds, results will be visible by the first afternoon – bubbling up of oxygen, foul odour 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.

Before You Dose
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. Learn more about opening your pond for spring.

Timing Your 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


Alternate Dosing For Ponds with Significant Algae buildup
Nualgi Ponds should be dosed every 5 days where algae covers 20% of the Pond. Reduce dosage to once per 7 days after algae drops to 10% of the pond.

How To Dose
Extract the appropriate dose and dilute in appropriate amount of water. 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.

Storage
Store in a dark cool place – Nualgi does not need to be refrigerated but should be stored away from direct light.
