Nualgi is an innovative new product that helps freshwater and saltwater aquarium owners safely improve the natural balance of their tank and enhance the health of their fish, plants and coral.

Nualgi Aquarium solves three primary challenges by: helping the tank stay algae-free, keeping the water clear and oxygen-rich, and increasing the health of your aquatic inhabitants.

It’s pretty amazing, and ultra-scientific. But Nualgi works to improve your “Nano Silica” base so it carries nutrients to the good algae, which start to multiply and consume the bad algae’s food, thereby robbing the nuisance algae of the gunk it needs to survive.
