Bio-Cubes are made from 100% biologically degradable polymers that effectively remove nitrates from both marine and freshwater systems.

Bio-Cubes have a very high surface area and contains 400% more carbohydrates than any other brand, making it the best product of it’s kind in the world. Bacteria consume the high carbohydrate source found in the Bio-Cubes and form a biomass that absorbs nitrates from the water in the aquarium. This biomass is then skimmed out with a protein skimmer or is consumed as a food source by corals and clams.

BIO-Cubes are very versatile and can be used in filter bags, fluidized reactors and denitrators. BIO-Cubes require no maintenance and require no feeding dosages making it the easiest and most convenient nitrate removing product on the market. Nitra-Guard BIO-Cubes comes with a free filter bag with every jar.

500 ml treats up to 174 gallons depending on Nitrate Levels.


Directions for Use:
The amount required will depend on stocking densities and amount of Nitrate in the aquarium. If Phosphate levels are very low (less than 2% of total Nitrate) use Nitra-Guard BIO-Cubes TITANIUM instead.
