I wonder if anyone has ever done the math on how much (in L or kg) water is moved by the moon each day. It's got to be something absurd.

    I have to assume it's about one moon's worth, divided by the distance squared.

    That would be its total pull, not just the water.

    We probably can estimate the amount of water that's at a different level from what a moonless Earth would.

    We could also say that technically all water is moved somewhat, because gravity is like that.
