xKeep Aquarium Water Crystal Clear with Top Fin EF-S Cartridges
This value pack is designed to sustain filtration for months in tanks that use the Top Fin BFS BettaFlow Filter or Desktop Aquariums with Element Filters. Each cartridge measures 2.1 inches long by 3.7 inches wide and uses activated carbon to help manage common tank impurities, supporting a healthier, more visually inviting aquarium.
How the EF-S Cartridges work
