I’m in the process of setting up my new Aqueon 5 gallon MiniBow. So the filter included uses filter cartridges and just doesn’t look adequate to me. So I bought a Hikari mini sponge filter, hikari check valve, tetra whisper air pump, and penn place airline tubing. Does anyone have any experience with this sponge filter or air pump, and will this sponge filter be enough on it’s own to properly filter my water? If not what else should I add? Also the air pump is going to be below my aquarium either on a shelf on the aquarium stand or on the floor. Can anyone tell me if it’s okay to put an air pump on the floor? Thanks!
