I use a U tube type overflow.Place a piece of airline tubing in the U tube. Place the U tube in place, one end in the tanks box the other end in the box outside the tank. Ensure that both ends of the U tube are under water(you will most likely have to add water to the O/S box) Now just suck the ir out of the tube and your siphon should start. Caution (salt water tastes pretty nasty )
