well I have figured out most of what I am going to do with my setup but the last thing I am stuck on is filtration.. I really like the emperor 400 and I already have one that is cycled so I would have a jump on cycling the tank. I was wondering if 2 of these and maybe 1-2 powerheads on my undergravel filter will be enough filtration? The emperor 400 is only rated for 80 gallons which gives my a total of 160 gallons.. I would like to stay away from canister filters or wet/dry. I already have a magnum 350 if I have to use it. but I really don't like them. any help would be greatly appreciated.. thanks again everyone
