Unless there is a way to split the intake and output tubes it isn't possible. I have never heard of anyone doing this before. If you have two 40 gallon tanks, I would be more tempted to use two XP2's I have a 75 gallons and my xp3 really moves the water. I would fear that it might be too much power for a 40 gallon tank. Going the route of two smaller filters would be more expensive than one xp3 though. Do you have turtles in both tanks? Because I was looking at ratings based on 2-3 times the size of the tank.
