Dee,I have the Eheim Pro II 2028 but would recommend the 2217's for simplicity. What size tank are you filtering?
I love the 2260 and 2262 filters!!!! They blow the 2028 out of the room, no comparison.
I am using a 2260 and an FX5 on a 125G six foot long tank. I didn't really need the FX5 but the boyfriend bought it new because he didn't know I bought a used 2260.
I am not personally familiar with the Eheim Pro 3 filters at all.
The 2217 filter has individual Quick Disconnect valves on the input & output hoses, it is completely different than the 2028 Pro II and Pro3 model filters.
