I don't own one but I follow another list also and they all have been talking about the Aquatop Canisters everyone who has them seem to like it and you can get the largest model for about the same as two AC110's. I own a C530 Marineland and to me the Aquatop looks just like it. I know they say the media from ML will fit
The AC110 has one gigantic compartment similar to a miniature canister filter, put the sponge that comes with the ac110 on the bottom, then the biomax rings on top of it. done.
