I have a 2232 and it's so far impressed me quite a bit. Dead quiet and powerful enough to give a decent current but not so powerful it blows fish and sand around. It's only been a week but already it has shown it's worth and flexibility. I've got it with some shelldwellers that have destroyed indirectly four previous filters and/or powerheads and this one hasn't so much as coughed.
I've had one running for years, I show it no mercy on an overstocked pairing tank. It's an excellent bio filter, as all Eheim canisters are, but it lacks a little in mechanical filtration for what I'm using it for. I'm sure on an average stocked tank this wouldn't be a problem.
