If you are sitting or squatting next to the toilet turn the nut clockwise. If you are laying on your back looking up at the nut, turn counter-clockwise. It helps to simulate opening a jar, then turn your wrists to match your view angle. Don't forget to have a bucket handy, and you will probably need a sponge to soak up the remaining water in the tank.
