Please take a look at this picture of my plaster. New pool has been in use for 4 months now. We noticed the marks about 1-2 months after pool's completion. The entire bottom of our pool has these streaky marks on it. Up close, these streaks appear to have tiny holes on them (like bubbles were popped on the surface). Mostly, the pool walls don't have these marks and look smooth and solid white, which makes us wonder why the bottom of the pool has these marks? If anyone knows what this is, and if it can be remedied, please advise.
