NPX BioPlastics are pelletized 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. Why bother with dosing Vodka daily when you can just use NPX BioPlastics and let the bacteria work for you?
