Aqueon QuietFlow E Internal Power Filters Medium Black 5.75" x 3.94" x 8.19"

Upgrade your aquarium filtration with the Aqueon QuietFlow E Internal Power Filter in Medium. Designed for aquariums up to 20 gallons, this compact internal filter delivers three-stage filtration — chemical, biological, and mechanical — all in one easy-to-install unit. The auto-start pump requires no priming and automatically restarts if power is interrupted, so your filtration never skips a beat.

Versatile mounting options let you attach the filter using suction cups or hang it on the aquarium rim, making it compatible with both frameless and framed tanks. The included Carbon Cartridge removes odors and discoloration, the Bioholster fosters beneficial biological bacteria to eliminate toxic ammonia and nitrites, and the Coarse Media Sponge traps particles and debris for mechanically clean water.
