Did you ever get the bottom of this issue? We are having the same problem, our PC did a no drain acid wash and it looked great for about a week also and then come back pretty much all at once. We think it was due to calcium being added to the plaster when applied. Our pool was a re-plaster not original but that shouldn't matter.
