Essential Nutrients for Freshwater Tanks

Improve fish health & reduce nuisance algae!


Nualgi is an innovative new aquarium supplement that uses nano-technology to help safely deliver nutrients that are typically lacking in a freshwater aquarium. Our patented formula uses a nano-sized silica molecule that becomes both the carrier for other nutrients and the nutrient by itself.

It contains a special formulation of Fe, Mn, Zn, Co, Cu, Mo, B, S, Ca, Mg, P, K & Si


By providing essential macro and micro-nutrients in a formula specifically designed to promote Diatom growth, Nualgi Aquarium is able to safely deliver more of the nutrients your freshwater tank inhabitants need to grow and thrive.

Within 3 – 5 hours of applying just a few drops of Nualgi Aquarium to your tank, a bloom of Diatom algae will develop. The diatom algae bloom out-competes nuisance algae for N, P and other nutrients, causing the bad algae to die off, then locks away some of the harmful nutrients in your tank in the new bio mass that is consumed as live food for your fish, snails & shrimp.


With just a few drops a week, Nualgi Aquarium helps freshwater tank owners with the following benefits:

  1. Crystal clear water.
  2. Fewer water changes and less maintenance.
  3. Reduced nuisance algae.
  4. Fresh food and improved health for fish and plants.

The results speak for themselves!

I saw a big change in my freshwater planted tank that had hair algae growing out of control. The hair algae has completely diminished and there are no signs of it coming back.

The progress I have seen in the tank after just for days is incredible. Try this stuff out you will not regret it.
