I just recently switched from a cheap HOB from Top Fin to an Eheim Classic 2215 for my 29G tank. What a filter. I can't really say enough good things about it. I went from foul smelling, cloudy water to crystal clear, odor free water in a matter of days. Best cash I ever spent.
Anyway, enough of that.
What do most people suggest as far as cleaning a canister? I currently have some pillow batting on the top layer, and pretty much replace that weekly. However, I have never touched (on the advice of searching here) the rest of the other media that came with the filter. The kit came with the ceramic "noodles" as well as Eheim's EhfiSubstrat Pro. There is also a course pad between the noodles and the EhfiSubstrat Pro. I assume I should clean the pads and noodles, but leave the EhfiSubstrat alone, since that houses my bacteria.
How often should I gingerly clean the rest?
