Just thought I should share this with you. My LFS is closing the day after tomorrow and the owner gave me a brand new Eheim Ecco 2231 canister filter for FREE! It was a PITA to set up, but once I got it all set up, it is powerful.
I have 5 Eheim canisters, the oldest being a Classic 2213 which I have had for over 15 yrs and just had to replace the impeller due to my dumbass. Too many beers and decided to clean the filter.
I have a 2260 (This is a beast), 2 Pro II 2060's, Classic 2213, Ecco 2232 ( I should have bought another classic ). You got a great deal getting it for free, but IMO, the Ecco line is a turkey. They dont hold as much media as the comparable classic models and the primer handle will break at the pivot point if you are not careful.
