Hey guys. At the moment I currently have 2 x eheim 2217's on my 4ft x 2ft x 2ft and in one of them I am using the recommended EHEIM MECH on the bottom, 1 coarse filter pad blue, EHEIM SUBSTRAT pro and 1 fine filter pad white which came with filter when I purcahsed it. However on my other one I am mainly using blue coarse filter pads as mechanical filtration with 1 fine filter pad on top and some EHEIM MECH on the bottom (which is also recommended in the intro booklet) and I have been finding that since I set this filter up at least 18 months ago, it slows down in flow and needs more regular cleaning than the other 2217 does.
Do you guys think that the mainly mechanical filter media I have chosen for my 'other' filter is a wise choice?
The tank mainly holds eartheaters and pleco catfish and I don't plan on changing the filter media over but I was just curious as to what your opinions are.
Thanks alot for your help.
