From Pathfinder Wiki

Therefore, when the ocean is on the opposite side of the earth relative to the moon, it is farther away, and the moon does indeed pull on it less than when the ocean is nearest the moon. But the moon is pulling at the rigid part of the earth's center which is closer to the moon, with the effect that the moon is pulling on the rigid portion with more force than it is pulling on the more distant ocean. In other words, we get a second high tide each day when the ocean is farthest from the moon because the moon is pulling the earth away from its ocean.
