I have a new Odyssea B28 Tank (28gallons) it looks similar to the Jebo ones. It came with sponge type filter system on the hood. I'm not sure if that's sufficient enough for a filtration system. I was thinking about getting a protein skimmer but the hood isn't designed to have any hang-on tank attachments only room for hoses and cords. Please advise. Thanks in advance for any input...
