So I'm new to keeping aquariums and I currently have a 60 gallon cube (24x24x24) that's cycling. Unfortunately, I didn't know about fishless cycling (wish I had), and we're about a month in with 6 tiger barbs. I have a Marineland penguin 350 on the tank, however, I'd like to upgrade the filter eventually (we're talking probably at least 6 months down the road). I was looking at canister filters and was wondering which brands were recommended and which size would be needed for my tank.
