Product Features

Effective biochemical filtration

hygger Betta Fish Tank Filter is made from food-grade materials, it is equipped with 4 environmentally-friendly filter sponges to filter impurities in water more effectively.

Cultivation of beneficial bacteria

The ribbed sponge has a large surface area, which facilitates the colonization of nitrifying bacteria and accelerated circulation, it can also absorb fine particles to achieve the effect of purifying water.

Improve dissolved oxygen

The combined use of air pumps can increase the oxygen level in the water, which would achieve oxygenation and dual biological filtration, and keep the water clean for your betta fish tank.

Energy saving without noise

Instead of using a power device, this tank sponge filter uses the air pump as the driving force. So there is no noise during operation. The sponge filter’s outlet pipe can be adjusted so that you can change the direction and height of the water flow.

Replaceable filter media

The filter comes with two kinds of filter materials: Filter sponge (including 2 spares) and filter box (including filter ceramic ball). Biochemical cotton can be cleaned or replaced. The filter cartridge media can be replaced with other media such as carbon and ammonia absorbent. You can easily remove the sponges from the filter for cleaning or replacement.
