Sponge filters have been roughly almost since aquarium-keeping started. However, many aquarium owners either have no notion of what they are utilized for or don’t understand they exist.
Although sponge filters aren’t appropriate for every tank, there are circumstances in which they are ideal.
They arrive in different shapes and sizes and pore dimensions, permitting them to be adapted to diverse filtration needs.
They can be powered in some ways, including air pumps, powerheads, or even another type of filter.
What is a sponge filter?
Sponge filters are cost-effective and specific norms for filtering aquarium water.
They furnish mechanical filtration and can guide a better population of healthful bacteria in your aquarium and, thus, a more balanced aquatic ecosystem.
Utilizing Sponge Filters for Soft Filtration
Sponge filters are perfect when secure and gentle filtration is required, such as in a fry tank where young fish could be stunk into the intake of standard filters.
Fish species such as bettas that do not succeed in strong winds also benefit from sponge filters.
Shrimp are another species that needs very gentle filtration instead of a vital intake to suck them in.
Sponge filters are fantastic for hospital tanks, where fish are often weak and cannot tolerate the more powerful suction from a standard filter inlet.
Sponge Filters for a New Aquarium
Another benefit of sponge filters is to jump-start a new aquarium.
To develop biological colonies, a sponge filter can be run on a well-established aquarium for several weeks or months.
Once the fresh aquarium is set up, the grown sponge can be set in a water bag and moved directly to the new tank, thus keeping the biologicals.
This offers the new tank an immediate biological increase, which helps the fish in the new aquarium by lowering the ammonia and nitrite spikes experienced in a new tank.
Some aquarium owners maintain a mall sponge filter operating in one or more of their main tanks, so they are organized to set up a new aquarium or an emergency tank.
Sponge filters perform nicely as a pre-filter on the inlet of a canister filter.
The sponge filters out the more comprehensive particulate matter, which holds the canister from clogging.
Cleaning or replacing the sponge pre-filter is far more comfortable than tearing apart the canister filter.
Another natural filtration is also furnished this way, and the sponge is prepared for use in setting up an emergency aquarium should the essentials arise.
When using sponge filters either with an air pump, powerhead, canister, or another filter, keep in mind that multiple sponges may be used.
This provides additional biological and mechanical filtering ability and allows maintenance to be surprised, so not all sponges are disturbed simultaneously.
It also provides the owner an extra sponge or two to seed a new tank with, if desired.
Downsides of Sponge Filters
The most significant negative when utilizing sponge filters is the lack of chemical filtration.
Sponge filters have no means to contain chemical media, suggesting they can only deliver mechanical and biological filtration.
Indeed, an aquarium with whole mechanical and biological filtration has the tiniest condition for chemical filtration.
Many specialists believe that’s not a nay, as they sense chemical filtration is not all that it’s broken up to be.
Another evident negative with sponge filtration is that they are not aesthetically attractive.
Who desires a giant old sponge detracting from the looks of their aquarium?
However, the impression can be minimized considerably if the placement is well designed for setting up the aquarium.
This is primarily true in a well-planted aquarium, which can conceal most equipment, including a sponge filter.
Sponge Filter Maintenance
Sponge filters are reasonably easy to keep.
The key is to remember to accomplish the maintenance regularly.
The best way to wash a sponge is to achieve a water change and keep some of the water that was just released.
Dip the sponge in the utilized aquarium water, gently press and remove the sponge several times to dislodge the accumulated particulate matter.
If this is accomplished every few weeks, the sponge will never clog entirely and last a long time.
Sponge filters are usually used in multiples, either with 2 inlets or by piling one sponge on top of another.
If there are multiple sponges, stagger the cleaning schedule, so they are not all done simultaneously.
This will reduce the impact on the biological colonies and minimize the potential for ammonia or nitrite spikes after cleaning.
