Sponge filter uses bubbles of air from an external air pump, or an integral water pump to draw water through the sponge.
The sponge need to be rinsed about every 2 to 4 weeks. It’s helpful to wash the sponge gently with water from the fish tank instead of tap water.
It is good to replace the sponge after 3 to 6 months’ usage as the holes of sponge is gradually clogged by the tiny debris.
