So I was looking to do a 20 gallon sump for my 55 gallon freshwater tank and it will not fit in my cabinet so I was wondering could I set the 20 gallon on a stand beside it and use 2 of the exact same pumps and put one in my 55 for the intake into the sump then use the other pump as a return in the sump to pump water back into the display tank. In theory it should work since the exact same amount of water is being pumped in as is being pumped out right? Any help on this would be greatly appreciated.
