I will drop the ugf. How about if I add another Emperor 400? I hated my canisters when I had them before. They were messy and pulling out the filter mediums to change them was a pain. Also one night one of the hoses came loose and flooded my living room

75 gallons of water all over the floor

. Im open to suggestion as far as filtering goes or anything for that matter. I just wanted to stay away from canister filters if I can. I may not be able to though. The gravel Im using from the other tank I had at a depth of 4 inches. Without a ugf will I need to lessen that or will I be fine? Thanks again
