Ok, I got another 135 awhile back. The difference in this one is it was free and the tank is 3'x2'x3' Im thinking about selling it though... but for now, I need a filter. It came with one, and things where going good untill I put my two catfish in there. So Im looking to make a filter for it. Does anyone have a good idea of what I should try to make? Or something that someone has already done that would be good for it? Thanks
