Aquarium Advice Freak
So I bought a fountain pump on clearance from the hardware store and am making my own canister filter using a gallon Rubbermaid jug. I was wondering if anyone had any ideas for non fish store aquarium medium to put in the canister. So far I am going Gravel, sponge, pot scrubbers, pillow stuffing, and coarse sponge. Most of it I know polishes but I was thinking the sponge medium would work well along with the gravel to harbor good bacteria. The only thing I was thinking I'm missing is some type of carbon. Is this a pivotal piece of the equation? Also any thoughts on if it would ok to fully submerge the canister, the pump will be submerged, the canister should be Ok with the water coming out the spout right into the water, right?
