I filter a 120l with a 2213 and it does the job perfectly, although there is not many fish in it.
In my opinion a 2215 would be ideal, although nothing wrong with going for the larger model. The eheim classics are in my opinion brilliant. They are designed in a way that all the water passing through the filter contacts the media which I believe is unique to them and they hold a lot of media for their size. Plus they are quiet, I have a 2217 on a difference tank and with it in the cabinet the internal fluval U4 is more audible.
And don't get too hung up on flow rate, how good a filter is depends on lots of other things too.
