I have a 60 gallon tank that I have just set up about two weeks ago. My tank isn't set up for a sump, so I have everything hang on the back. I have also reused my Marineland C-360 canister filter as well for the tank, mainly for mechanical filtration, but I have some rocks and two bags of chemi pure. My question is do I really need the canister filter. It keeps blowing micro bubble into the tank and I don't like/want that. I'm not opposed to removing it and putting a powerhead or two in its place. What are your thoughts and opinions?
