Hi All I was just thinking of ways to same cash an want to cut my electric bill alittle and though that I could plume my Q-tank in with my main tank. As long as there are no sick fish or meds in the tank and shut off its filter. I would install shut off system so if a fish was sick I would shut off the flow to the main tank and turn on the Q-tank filter. Good Idea?? I could shut off the heater also the main tanks heater can handle the 10gal Q-tank.
