“loving the canister. very quiet”
“The recommended tank sizes are pretty useless. I have a 2217 on a 75 gallon, and I'm thinking of adding a second one. Wouldn't be anywhere close to enough for a 125.”
“My life would be easier and my tanks would look better if I had only bought Fluvals!”
“If I had to choose again I'd probably buy two Eheim. Though the Fluval is a bit easier to maintain and it does suck up fish waste better, the noisy impeller and crappy build quality of it has kind of turned me off it.”
“They are great canister filters. They dont provide that much water flow output for that size tank. They dont have self-priming. They are great when used to hold phosphate,carbon,and nitrate media.”
“I just looked over the specs for the Eheim 2217 and IMHO you have about half the filter you need. Just not enough available volume to support a well-stocked 100-gal tank.”
“They should re make this filter and just add a self priming feature then it would be perfect”
“I really think the EHEIM classics are the best filters out there for reliability and longevity”
“My 120 has a eheim 2217 or is it 2117 classic on one side and the fx6 on the other side. The eheim is basically useless and i strongly recommend avoiding them.”
“It used to start up fine when I plugged it back in after re-filling the tank, but now I have to pick it up and shake it vigorously to get it to start.”
“Bought a new one from Big Al's, NEVER had to open the instructions”
“i solved noisy brand new classic 600 (2217) with greasing ceramic shaft”
“I have an Eheim 2217 on my 75g cichlid tank that sprung a leak recently. The leak is on the output side where the male and female connectors are.”
“I would recommend getting the eheim classic 2217 the flow is adjustable with ball valves so no worries with too much flow + spraybar and there are so many different media combinations so u can add what u need and remove what u don't.. Always starts easy to remove and clean..”
“Never had a tank this easy to maintain before. Over-filtration is gud.”
“I am currently running a 2217 on a 55g and I am not satisfied, I am getting another one. My 406 on the other hand makes waves in a 55g.”
“The other canister on this tank is the Eheim 2217, which I went to clean the other day and realized how much I despise THAT filter.”
“I bought mine from Big Al's and have LOVED it for years.”
“Just cleaned both my filters today and fluval was ten times easier. Couldn't get the eheim lid off till it fell onto my foot”
“I have one with my classic 2217 and it's basically the exact same canister but without the motor and it goes in front of the motored version, connected with hose of course.”
“It's the empeller. I have no idea how it's broken after 1 week of use, and I am honestly surprised in a bad way.”
“You might also consider the Eheim Classic 2217. The filter media doesn't come in easy to lift baskets, so a little annoying for maintenance. Otherwise, its a great filter.”
“I just bought the 2217 model for my 75 gallon for about 130$ off Big Als Online.”
“I didnt like my 2217s at all. They were terrible at mechanical filtration and thats with powerheads helping out and everytime I would do a large water change and lost the siphon from the water falling below the intake, it was a pain in butt to get it going again.”
Practical notes owners raise — setup, quirks, and issues to watch for. They don't say whether the person likes the product, so they're not counted in the score, but they inform the pros, cons, and who it's for.
“I run 2 of the 2217 on my 180g. I get the occasional grinding/gurgling after I clean my 2217 but generally that is an air pocket and one tilt of the filter and viola, gone.”
“My Eheim 2217 filter is about 18-20 months old. I recently cleaned the filter and hoses, everything was whisper quiet prior to that.”
“I run a 2217 on my heavily planted, lightly stocked 29 gallon. I don't think this would be too much at all.”
“This is an Eheim 2217 on a 57g freshwater tank.”
