NPX Bio-Activated Polymer is a pelleted nitrate and phosphate reducing filter media designed for use in fluidized reactors. Made from 100% pure carbon polymer, it optimizes water quality and reduces maintenance by supporting the growth of denitrifying bacteria. Ideal for freshwater, saltwater and reef applications.
The manufacturer recommends using NPX Bio-Activated Polymer in a media reactor to ensure constant motion and water flow. Use of an efficient protein skimmer is also recommended for reef applications. This 200 ml container treats up to 50 gallons. Made in the U.S.A.
