How do sponge filters work?
It is necessary to employ a sponge filter (which is placed within the tank), an air pump (which is situated outside the tank), and airline tubing to connect them all to get the most basic filtering results.

Water is pulled through the sponge walls by bubbles that rise from the sponge’s interior and travel through the sponge walls. This water suction system automatically collects garbage from the aquarium while also providing a growth habitat for beneficial bacteria to flourish.
Sponge filters have long been a favourite of both new and experienced fish keepers due to their low cost, ease of cleaning, and lack of mechanical parts.
It offers strong water circulation and surface agitation due to the continual bubbling while remaining moderate enough to prevent sucking up a fish fry, shrimp, and other slow-moving organisms.
