Description
Suitable for 10-30ltr aquarium tank
This Air driven, dual sponge filter system is a motor free filter, super quiet, only the smoothing sound of bubble bursting in the water surface. Its tiny and thin design make this filter so compact that can suit up to 19L aquariums. This internal filter must be run by air pump (at least 3-watt) and equipped with a check valve on the air tube to prevent flow-back. Single filter measures 19.3×10.5 x 2 cm, recommend for 7.5–19L freshwater and saltwater aquariums.
Effective Filtration
Mechanical pre-filter sponge captures debris and activated carbon for clean, clear aquarium water. Mini white bubbler stone produces constant, soft bubbles to agitate water, slow flow. Great for betta fish, fry, and shrimp. Dual sponge filter kit comes with 1 filter + 3 packs filter cartridges + 1 white air stone +Â 1 hanging clips.
Replace filter cartridge every 2-4 weeks depends on how many fish you house.
Easy to install
Connect sponge filter with air tubing to air pump and ready to go (please note that 3/16-inch air tubing and air pump are excluded). Two suction cups and one hanger helps filter stays in place, no floating. Must be install vertically.
