• Easy to use filter material for phosphate and nitrate reduction in a salt-water aquarium
• The 100% biodegradable polymer biopellets NP offer both a surface area and source of nutrients at the same time for phosphate and nitrate-reducing bacteria
• During their growth the bacteria use the biopellets NP as an organic carbon source (energy source), phosphate and nitrate of the aquarium's water as a source of nitrogen and phosphorus
• Model number: 81517

Directions Add the biopellets to the filter media, ensuring they are fully submerged in the water. The bacteria present in the aquarium will use the biopellets as an organic carbon source, phosphate and nitrate from the water as a source of nitrogen and phosphorus. The bacteria will grow and reduce the levels of phosphate and nitrate in the aquarium water.
