I am curious....Does anyone have any suggestions. I want to set-up five 5 or 10 gallon tanks for various fish. I figure the easiest thing would be to drain all of them into the same filter and use pipping to pump the water back. The only problem I have is that I have no idea how to get the water from the tanks to the wet dry without an overflow system. I am not sure if I am explaining what I want o do correctly. Please help.
