I voted for the Eheim 2217, I have the 2215 and it does an excellent job not to mention in the 15 or 16 years I own this filter and have never had to replace a single part, and it's dead silent. I tried all of the popular brands back then the magnums and fluvals because they were less expensive and wound up returning them, added the additional money and got the 2215 and have never looked back. I just bought a monster Eheim 2080 (Didn't care what it cost) for my 120 FOWLR
build and in about 7 days the ammonia was gone and nitrites at day 12 are starting to drop (I know it's not just the filter but it does have a good part to do with it), as big as it is, it too is silent. Oh did i mention both of my tanks are so clear they don't look like they even have any water in them. Sorry for carrying on, I just love Eheim products, It's an emotional thing.
All kidding aside, Eheim's do cost more but I feel they are well worth the price of admission.
