Nitrate & Phosphate Reducing Polymer Media

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?


Directions: NPX Bioplastics are best installed in a fluidized filter like the PhosBan reactor 150 or 550, but they may simply be placed in a media bag in a filtration compartment. Use 100 ml Bioplastics per 100 L (approx 25 gallons). After 2-4 weeks, nitrate and phosphate levels will decrease. because NPX Bioplastics are slowly consumed, more pellets have to be added periodically. Observe the level of media within the filter and top off as necessary about every 3-6 months. For aquaria with heavy feeding, higher quantities can be used, but the accumulation of phosphate from the food may require the combined use of NPX Bioplastics and PhosBan granular ferric oxide media, in separate reactors.
