BIO-Cubes have a very high surface area and contains 400% more carbohydrates than any other brand, making it the best product of its kind in the world. Independent testing in real world scenarios, have proven BIO-Cubes to far outperform all other competing products. No other product of its kind can compare with the explosive performance that BIO-Cubes can offer. 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 and phosphate removing product on the market. Nitra-Guard BIO-Cubes comes with a free filter bag with every jar (excluding 5000ml size). How it all works Bacteria consume the high carbohydrate source found in the BIO-Cubes and form a biomass that absorbs nitrates and phosphates 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. When culturing bacteria, 2 of the most important factors that will determine the size of the colony are surface area and food source. BIO-Cubes look like small open celled sponge
