I just ordered a sunsun canister filter for my 26 gallon fw
. I have never had a canister before so I'm new to all the media options available. There are 3 baskets - do I need the white pads in all 3 baskets? Or do they all go on the bottom? I'm not going to use the carbon - I was going to get some ceramic rings - do they need to be in a bag or keep them loose? Do I need bio balls or is that the same as ceramic rings? Sorry for all the newb questions. I just need recommendations of what to put in each basket.
