Advanced Aquarium Biochemical Filtration System

Biochemical Filtration: Powered by an air pump, this filtration system combines mechanical and biological filtration principles to deliver superior water purification. The multi-level filtration process effectively absorbs fine particles, ensuring crystal-clear water without disturbing your fish.

Changeable Filter Material: Customize your filtration needs with two types of replaceable filter materials: sponge and ceramic filter balls. Easily remove and clean the sponges, with a total of 4 included. Additionally, 2 media boxes with ceramic filters are provided to enhance cleaning efficiency or accommodate other filter media.

Easy to Use: Simply connect a 4mm air hose from your air pump to this tank filter. The adjustable outlet pipe allows you to modify the direction and height of the water flow for optimal performance. (Note: Pump and air hose not included; select a suitable pump based on your tank size.)

Upgrade Filter: Experience increased water dissolution with this ultra-quiet, clog-resistant aquarium filter. Its multi-layer filter cotton design offers a large surface area for comprehensive filtration. The strong suction cup ensures secure attachment, while the bottom direction is rotatable by 360 degrees.

Suitable Size: Designed for medium-sized tanks, the sponge filter measures 6.3 inches in width and adjusts from 9 inches to 13 inches in height, with an inner circle diameter of 0.59 inches. Ideal for 15 to 55-gallon tanks; larger tanks may require two filters. Perfect for shrimp tanks, betta fish tanks, breeding ponds, goldfish, discus, crayfish, deep-fresh fish, juvenile fish, and more.
