The tides work because water flows across the surface of the rigid Earth. You have a body that holds your water in, and a far more massive, much closer object than the moon, exerting far, far more gravitational pull on you than the moon. Also, the moon is approximately the same every day (but higher or lower in the sky). It looks different on different days due to shadows, not gravity.
