I have a 75 cichlid tank with an emperor 400, and now an AC110, and I gotta say I love the AC110 already over the 400. Obviously, the flow rate is better, but the biological aspect of the AC110 is better IMO.
Yea, i like it a lot. The only thing I like about the 400 more then the AC110 is the way chemical media is held, other then that, cant really complain.
