The reason the water on the opposite side of the Earth from the moon bulges is because the center of mass of the combined Earth-Moon system is not at the earth's center, but much closer to the moon side of the Earth. The Earth-Moon system rotates about this center of mass, and consequently the water on the far side of the earth is flung outwards, creating the bulge.
