NP-Minus BioPellets 1000ml

NP-Minus BioPellets for seawater for nitrate and phosphate reduction Important: Operation ONLY in biopellet reactor or fluidised bed filter ! The highly effective NP-Minus BioPellets consist of 100% biodegradable polymers. These dissolve over a period of several months and act as a carbon source for aerobic bacteria and other microorganisms. The pellets are a food source for these microorganisms. Together with the nitrate and phosphate, which are usually present in excess in the aquarium water due to metabolic processes, microbial biomass is thus formed.
