Sure..that will work. As will a check valve. Put both in place. I'm just saying that I would not want to be THAT dependent on those working...because if they fail during a power outage you are talking about complete death of the tank and flood damage to your house.

The holes WILL plug up. You'll need to keep those cleaned out all the time.

Check valves get stuck open. Especially if they don't get exercised much.

My returns go over the top edge of the aquarium and exit only 2" below water line. Even if my check valve fails, there is no way I can siphon more than 2" of water from the tank. Design to be fail proof. You'll sleep better.
