Another use for bio sponge filters is to jump-start a new aquarium. A sponge filter can be run on a well-established aquarium for several weeks or months to establish biological colonies.

Once the new aquarium is set up, the matured sponge can be placed in a bag of water and transferred directly to the new tank, thus maintaining the biologicals.

This gives the new tank an immediate biological boost, which in turn benefits the fish in the new aquarium by reducing the ammonia and nitrite spikes experienced in a new tank.

Some aquarium owners do keep a small sponge filter running all the time in one or more of their tanks, as a result, he or she is prepared for any emergency.

Submersible Bio Sponge filters work well as a pre-filter on the inlet of a canister filter. The sponge filters out a good deal of the larger particulate matter, which keeps the canister from clogging.
