Aquarium Masters AM Filter Nano Cartridge - 3 Pack

Rite-Fit Whisper Bio-Bag® S, AM Nano Cartridge - 3 Pack

Rite-Fit Cartridges for Whisper®  & Aquarium Masters Power Filters offer superior filtration, helping to create and maintain a healthy and crystal clear aquarium. These filter cartridges utilize powerful multi-stage filtration with fast-acting premium activated carbon to remove discoloration, odors, and organic impurities from your aquarium. Carbon inside of the cartridge is evenly distributed with the use of an internal grid frame, increasing water contact time and improving the effectiveness of chemical filtration. Also contributing to the effectiveness of these filters are dense floss traps, which remove free-floating dirt and debris, and biological filtration provided by beneficial bacteria after it begins to grow across the wide surface of the cartridge. Simple to use, simply replace the Rite-Fit cartridge once every 2-4 weeks.
