How Does ItWork?

A sponge filter uses bubbles of air from an external air pump, or anintegral water pump to draw water through the sponge.

As water is drawn out through the lift tube or pump, it is replaced bywater entering the sponge.

The sponge is a mechanical filter and the surface of all the bubbles orpockets in the sponge provide a bed for the bacteria of a biological filter.

The bacteria help to break down harmful waste (ammonia and nitrite).Sponge filters provide both mechanical and biological filtration.

Most sponge filters are reasonably efficient filters for small volumetanks.

These filter are excellent for small size fish like dwarf cichlid, guppy,killifish etc., or for hatcheries, maternity tanks, and fry tanks, as thefilter produces minimal current and has almost no way to suck the fish throughthe filter.

Also, the air infusion chamber produces minute bubbles which increase theoxygen solubility.

WhatMaintenance Does It Require?

The sponge will need to be rinsed every time it becomes dirty, about onceevery 2 to 4 weeks.

It’s helpful to reserve the beneficial bacteria by washing the spongegently with water from the fish tank instead of tap water.

After 3 to 6 months’ usage, the micro holes of sponge is graduallyclogged by the tiny debris, the beneficial bacteria won’t have as much livingspace as before.

That’s when the sponge filter starts to lose its efficiency.

So it is also recommended to replace the sponge once every three to sixmonth or when the sponge gets worn out.
