How Does It Work?
A sponge filter uses bubbles of air from an external air pump, or an integral water pump to draw water through the sponge.
As water is drawn out through the lift tube or pump, it is replaced by water entering the sponge.
The surface of all the bubbles or pockets in the sponge provides a bed for the bacteria of a biological filter.
The bacteria help to break down harmful waste (ammonia and nitrite).
What Maintenance Does It Require?
The sponge will need to be rinsed every time it becomes dirty, about once every 2 to 4 weeks.
It’s helpful to reserve the beneficial bacteria by washing the sponge gently with water from the fish tank instead of tap water.
After 3 to 6 months’ usage, the micro holes of sponge is gradually clogged by the tiny debris, the beneficial bacteria won’t have as much living space as before.
So it is also recommended to replace the sponge once every three to six month or when the sponge gets worn out.
