welcome aboard, mike, and as for your Q
most of us here either have or eventually do go with a natural bio filter, so if you have a dsb and or lr and or a skimmer, then i would not reccomend any canister, too much money and they can be nitrate problems in the future, IMO,
live rock and a deep sand bed, is the best way to go, to pit off with a skimmer and some powerheads, and it will be much less maintenance, more effective and nicer looking in the long run, lr and the dsb are the best 2 filters(natural too, and less of a prob with nitrates later) that you can get for any system but if you are not ever gonna go reef or anything, canisters can do fine for a fish only tank, but the prob is most of us see what we can accommplish and eventually go reef(even if we say we wont), so if there is any doubt or intention about going reef, i would put the money into lr and sand instead(nad if you have them already, then a skimmer and powerheads)
