I run two A.C. 110's on my severely overstocked display tank. The water stays clear and the fish are thriving. I still use a 19 year old Marineland Emperor 280 bio wheel on my backup tank. It does a good job too. My only experience with a canister filter was a Marineland Magnum 330. Great filtration, very labor intensive cleaning.
I would recommend the A.C. 110. Once you make it through the initial month of vibration noises and master the little noise making quarks, it works really well. It takes about two minutes to clean. It holds a large amount of filter material, even more if you take out the charcoal. I've got to admit that the new Fluval canisters are tempting and I'm considering buying one. not because i need it. Just one more gizmo to play with.
