I'm a new owner of canister filters (Rena XP2). I have always used the HOB Aquaclear filters, so every week, I would rinse the media in fish water to get rid of the poop and such. Every month, I would actually take apart the entire filter and clean them with a brush to get rid of all the grime and such. Now that I've got a canister, I am still doing the same weekly maintainence as with the HOB filters (washing the media), but the one-month mark is approaching, I was wondering how you guys clean these canisters. Do you take apart all the tubes and scrub them down with one of those pipe cleaners as well as the motor housing? Or do you just clean the motor housing? Thanks
