I'm just wondering about a cheap and small filter for a Q tank. Would a sponge filter work?

Sponge filters are usually the most reccommended for Q tanks...Maybe because they are easy to keep cycled? I don't know, we'll have to wait for the experts

Sponge filters are perfect for a Q tank because they are cheap and are easy to maintain. You can also throw them away without losing a lot of money.

Most sponge filters also have a replacement sponge so all you have to replace is the sponge, not the whole filter. The rest could be sterilized in a weak bleach solution or out in the sun.
