I have a quarantine tank that I set up as permanent tank. It is 110G and has a sump. I know that is large but that's what I was able to find when I was replacing my DT. I set it up several months ago with some filter pads from my DT tank. I never purchased any fish. I now am getting ready to purchase some fish, so I replaced the filter pads with other filter pads from my DT. I put in some ammonia to insure that I have enough live bacteria. I am checking the parameters, however, I am not sure that the filter pads will be able to provide adequate bacteria for such a large tank. Do you have any other suggestions. I do have a canister filter, but I wanted to avoid using it, as it is a pain. Would bio balls in the sump or ceramic rings be better. Thanks
