QANVEE Aquarium Sponge Filter with Quiet Water Pump - M(15-50 Gallon)

If you have never seen this before, check out the video. This aquarium bubble sponge filter is powered by a super quiet water pump, eliminating the need for noisy air pump humming. It works as a bio sponge filter and as an "Air Pump." You can adjust the air intake knot to create fine bubbles and reduce the bubbling sound to almost none. It is easy to clean - simply squeeze it in tank water to avoid the death of good bacteria.

The package includes Filter S (for 8-30 Gallon) or Filter M (for 15-50 Gallon), 2 bags of hollow ceramic balls (or filled with other bio media), and 3 strong suction cups. Please note that the USB Adapter/Hub is not included. The media chamber box needs to be open by breaking off with both hands (like breaking off a stick). It is suitable for both freshwater and saltwater tanks. We have quality checked all the filters, so they should rarely have problems. You can buy with confidence. This sponge filter works without an air pump, is ultra quiet, and more efficient than other sponge filters. It is USB driven, 5V safety low voltage, and 2W energy saving. Simply plug in a USB adapter and you get a bio sponge filter and an "Air Pump." The air intake is adjustable to create lots of fine bubbles and reduce bubbling sounds, resulting in super quiet operation. Oxygen-rich water, combined with strong good-bacteria, can handle large amounts of ammonia and nitrite compared to other types of filters. It is suitable for small and large fish planted tanks, shrimp and breeding tanks, and more.
