Description of the Large Double Head Bio-Sponge Filter (XY-2822):

The 8 large double head bio-sponge filters provide both mechanical and biological filtration. Simply install an airline into the unit and provide both aeration and filtration for your fish. Aerobic bacteria colonize the sponge providing a bacterial substance to facilitate the nitrogen cycle. In addition, the sponge traps larger waste particles. It mechanically cleans the water without trapping baby fish.

These filters are useful as breeding filters, as a secondary filter or they can be used as pre-filtration unit by fitting to an external or a top filter.

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. In addition, the sponge is a mechanical filter and the surface of all the bubbles or pockets in the sponge provide a bed for the bacteria of a biological filter. The bacteria help to break down harmful waste such as ammonia and nitrite. Sponge filters provide both mechanical and biological filtration.

Most sponge filters are reasonably efficient filters for small volume tanks. These filters are great for small size fish or for hatcheries, maternity tanks, and fry tanks, as the filter produces minimal current and has almost no way to suck the fish through the filter.  Also, the air infusion chamber produces minute bubbles which increases the oxygen solubility.

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 keep the beneficial bacteria by washing the sponge gently with water from the fish tank instead of tap water.

After 3 to 6 months of usage, the micro holes of the sponge gradually become clogged by the tiny debris. Therefore, the beneficial bacteria will not have as much living space as before. And this is when the sponge filter starts to lose its efficiency.  So it is also recommended to replace the sponge once every three to six month or when the sponge gets worn out.
