The time has come to change out the media in my canister filter. It has different trays,so I use biochem zorb in the bottom tray them chemi pure in the second one up, then ceramic rings above that. My plan is to change the media and wash the inside of the canister. My question is should I wash the rings out too? This is where my bb build up I'm guessing, but I know it's gonna be "dirty" I also have a month old fuge with live rock & chaeto that I'm not touching. Thanks in advance
