either that or go with the eheim classic series. I'm now running an eheim 2215, a fluval 305, and a hydor koralia nano on my 46 bowfront planted tank, and the water is crystal clear. I just got the eheim 2215 in today, and it is an excellent filter, and much better than my fluval. The most noticeable difference is the amount of media in the eheim. There is about 10x the media in the eheim as compared to the fluval. Don't get me wrong, i like the fluval, but i feel like the eheim is a better filter overall.
Just my 2 cents
