• Aquarium nitrate and phosphate removing biopolymer filter media
  • Naturally reduce aquarium phosphate levels with beneficial bacteria
  • Bacteria uses up nitrate and phosphate as it grows on the filter media
  • Use bioplastic media in fluidized reactor


Two Little Fishies NPX Bioplastics is a biopolymer filter media that helps maintain aquarium water quality by supporting the growth of nitrate and phosphate reducing bacteria. Enjoy natural and cost-effective management of aquarium phosphate levels by cultivating beneficial bacteria!

NPX Bioplastics are pelletized biodegradable polymers you use in a fluidized reactor. As bacteria populate the pellet surfaces, excess growth sloughs off to be harvested by a protein skimmer or become a natural food source for filter-feeding invertebrates such as corals, clams and sponges. Anaerobic zones within the pellets promote conditions where bacteria associated with denitrification (nitrate removal) thrive. Use this natural approach in conjunction with protein skimmers and phosphate-removing media to combat high levels of nitrate and phosphate that pollute aquarium water quality.

Install NPX Bioplastics in a reactor for convenient nitrate and phosphate control. Allow time for bacterial population to reach effective levels. For best results, begin with smaller quantities and add more NPX Bioplastics as media becomes inoculated with beneficial bacteria. After two to four weeks, nitrate and phosphate levels will decrease. 200ml treats aquariums up to 190lt.

Use NPX Bioplastics in conjunction with proper aquarium filtration and employ strong water circulation and aeration. The use of NPX Bioplastics in marine aquariums must be accompanied by the use of a protein skimmer to achieve the export of bacteria and assimilated nutrients.
