I'm planning on setting up a 75 gallon tank for an oscar, and maybe a couple other fish. I know that a wet/dry would be best, but it probably won't work due to my DIY stand, and the fact that I'm nervous about setting up too much water on a 2nd story apartment. I've already invested in a marineland magnum 350 canister filter. I was wondering if I need to set up anything else for aeration and/or biological filtration? Quiet filters would be optimal. Thanks in advance.
