NP Bio Pellets are a unique carbon based polymer that doubles as a substrate and food source for aerobic and anaerobic bacteria. Like adding a liquid carbon source such as Vodka or VSV, we still cannot control what bacteria are growing–however, these pellets should inherently provide more control through the location that the bacterial growth occurs (on the pellets!). It has been referred to as the Solid Vodka method for the large bacterial biomass that can be generated and then exported via protein skimming. Reef Interests, the manufacturer of NP Bio Pellets, has stated they have a patent on their unique biodegradable polymer.
“NP-reducing BioPellets are composed of biologically degradable polymers that can be placed in a fluidized filter or filter canister. The pellets will allow aerobic growth of bacteria which consequently will consume nitrate and phosphate simultaneously. The bacteria will use up the carbon from the BioPellets, whilst nitrogen and phosphorus are taken from the water as nitrate and (ortho)phosphate. This conversion of organic BioPellets (together with inorganic nitrogen and phosphorus) into microbial biomass is called immobilization. In addition, anaerobic layers will develop, resulting in additional denitrification.”
