Well I personally like canisters, however, I never run a tank on only one filter (except heavily planted tanks). Even with wet/dry filters, I still would be running another couple (particularly mech filters) for backup.
Wet/dry or Cannister That is The Question

Wet/dry systems are gravity fed with a pump return. The main mechanical filtration limitation with them is the media. because of the design... you are limited to the type of media you can use. Go too fine with a W/D pre-filter and you create a roadblock.
A canister is...by design...a pressure system so you can use finer media for the mechanical filtration. YES this does reduce the rated flow of the unit but the flow continues... The smaller the media...the more particles are removed from the water.
This is the reason that I always recomend more than one type of filter system. Each type of filter does one or more things well but none of them excel at everything.
HOB filters catch a lot of suspended crap in the water and are very simple to change the media in....Canisters, bieng a pressure system can remove much smaller particles than any other type...(If you don't belive this is true then take a close look at an RO/DI system sometime.) ...air driven sponge filters are great for extra bio-filtration and as a safety net... and of course...A wet/dry sump system has huge bio filtration capacity and versitility.
Everything has its place...advantages...and disadvantages...

Ok Rally, You and Repair have convinced me........Ill call steve today and see what we need.....
it can run the 220 and the 150 I have next to it???

Yes it could providing that you have a big enough sump that can hold the water in a power outage.
I personally would not run a sump on 2 tanks.
If a disease breaks out in one tank it can easily spread to the other. I personally would just go to the extra effort of making 2 wet/drys. I think you would also achieve better water quality like that anyway as each tank has its own individual wet/dry.
