Media for Canister Filter?
I have a Fluval 300 canister filter in a 54 gallon freshwater tank. (No fish yet, just live plants.)
One of the 'advantages' the filter claimed was that I could add my own media to the little baskets. But how do I know what sort to use??
Right now I just have what came with the filter. Is that good enough, or should I be looking for other options?
