which canister should i go with?

go with the bigger number :)

actually i am looking to replace the Fluval 303 i have on my 55 and am trying to decide what to get now - its an african tank so need to over filter.
 
Get the Pro II 2026- have 2- great filters, quiet, reliable and well made. If you want overkill, go with the 2028.
 
Is that one eheim pro or two of the pros. Although it is a bigger filter, it is only one filter so if the filter should malfuntion in any way then the life support system for the fish will have shut down completly. In that case it would be better to have two filters so if one does happen to go down, then the fish will still have one filter on the system for them. If the choice is to only have one eheim pro or two eheim classics then I would have to say go with the eheim classics for this reason. If you put two eheim pros or a smaller version of the same then I would opt for that.

I've been very happy with my Pro II. Very quiet, easy to set up, huge media capacity and easy to maintain.

No experiance with the clasics.
 
agree with most above - I'd go with a couple 2215's. 2 filters is better than 1, and the 2215's are pretty good filters in their own right...
 
I have a 2215 on my 46g bow. It's doing a nice job and is quiet - circulation seems unaffected even though I had to throw a linen dish towel in the top to filter out some dying green algae (Euglenoids) after a blackout period.
 
RE: F&S sale - make sure they aren't backordered (mine came from BigAls 'cause of this), and be sure to look into whether or not you want the media, valves kit (you at least want the valves, trust me).
