Pelletised biodegradable polymers that provide a time-released source of food for bacteria that assimilate nitrate and phosphate.
As bacteria develop on the pellet surfaces, excess growth sloughs off due to the tumbling in a fluidized filter, and these bacteria can be removed with a protein skimmer or serve as planktonic food for filter-feeding invertebrates such as corals, clams, and sponges.
Anaerobic zones also develop within the pellets, thus promoting denitrification there.
NPX Bioplastics granular media made from biodegradable polymers. For use in a fluidized reactor.
The slow release of organic food from these plastics promotes the development of bacteria that assimilate nitrate and phosphate.
These bacteria can be harvested by protein skimmers, so that the nitrate and phosphate levels are naturally reduced.
The bacteria are also a food source for filter-feeding invertebrates such as corals, clams, sponges, and feather dusters.
