Oase FilterAction Nitrate Remover 120 g

Water treatment. Long-term active against nitrate. Co-substrate and microbiological colonization area in one. Can be placed directly in the filter thanks to the ready-to-use mesh bag. Reduces water changes. Increases carbonate hardness and decomposes completely. Suitable for freshwater and saltwater. Denitrifying anaerobic bacteria break down nitrate in the aquarium but require oxygen-free zones. If these are insufficient, nitrate levels rise, leading to algae and vulnerable fish. Nitrate Remover Pellets is the natural solution: the filter medium creates anaerobic zones, thereby improving water quality. It also slightly increases the water's carbonate hardness and stabilizes the pH level. Optimal in combination with the active denitrifiers in the KlarWasser Boost Mix bacteria.
