I've only hed my fluval for a couple of mos now. I thought you just changed filter pad and cleaned the media. But That makes more sense.RhomZilla said:Your talking about wet/dry. With any canisters, your gonna need to change the media within months, but not as much from time to time as with the rest. Just like an internal or a prefilter, you'll still need to do maintenance with a canister, but within a legnthier time.
