Hi, everyone.
First time poster and aquarium newbie here. Please excuse me and let me know if I did anything wrong regarding the forum rules here.
I have a clear bottom tank for goldfish. In my current setup, I have an underwater powerhead attached to a sponge filter. My sponge is getting very gross, like slimy and breaking into pieces. Routine cleaning of the sponge gives me goosebumps.
I am thinking about filling the filter canister with gravel instead of a sponge refill. Is it a good idea? My thinking is as follows:
When the power head pumps water thru the canister, the water passes over the gravel to form a biological filter. Will this create an equivalence of my original sponge filter? If not, what are the major differences and pros and cons of each approach?
