Essential Nutrients for Planted Tanks

Improves plant health, coloration & growth.


Nualgi is an innovative new aquarium supplement that uses nano-technology to help safely deliver nutrients that are typically lacking in an 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


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

  1. Improved plant health, coloration, and growth.
  2. Crystal clear water.
  3. Reduced nuisance algae.
  4. Reduced need for plant fertilizers.
  5. Fresh food for your plecos, snails, and shrimp!


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 aquatic plants need to flourish (Pun intended).

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.
