I'm trying to help my friend start a 5 gallon tank. I have a 20 gallon running tank with fish. I was wondering what I can do to speed up cycling the 5 gallon? Should I give him some of my water? Since his filter will be smaller than mine, I can't exactly give him filter media... would getting some water from my tank and soaking my filter in there for a minute or two then putting it in the small tank help? I also have the Nutrafin Cycle stuff. Any thoughts? Also out of curiosity, I assume all tanks cycle in the same amount of time... a smaller tank doesn't cycle quicker or anything does it?
