Today I bought an Eheim 2217 for my 55g, due to my poor knowledge on this filter I ended up with lots of water on the floor but eventually had it set up. I have heard comments that this filter makes no noise but mine had a slight hum to it(slightly louder than AC filter), is this normal?
Edit: Also can anyone tell me how to correctly prime this filter? I have no idea on how to get the air out.
