Biopellets NP is an easy to use filter material for reducing the nitrate and phosphate content in the marine water aquarium. The Biopellets NP consists to 100 % of biologically degradable polymers with the additional benefit of providing a surface area and nutrient source for nitrate-removing bacteria. As they grow, the bacteria use the Biopellets NP as an organic source of carbon (energy source) and the phosphate and nitrate in the aquarium water as a source of nitrogen and phosphor. The waste products nitrate and phosphate are converted into microbial biomass and then removed from the aquarium by skimming or as an additional feed source (bacterial plankton) by filter feeders, mussels, sponges and corals.
