On my 125 I have a FX5 and a Fluval 406 and currently have a eheim 2217 hooked up too. I'm overstocked on cichlids, hints the reason for the added filtration. I was considering getting rid of the 2217 for an AC 110. Reasoning behind this is the cleaning of the 2217 and priming. I spend at least 35 min when I clean the 2217 out. It has driven me nuts having to shake the canister all the way to flipping the canister upside down and holding it to prime it. It has the spray bar attached and it's a low flow set-up. So enlighten me.
