new pool plaster issues & questions

We just had a new gunite pool installed in our backyard and after the white marble plaster was finished, we noticed some stains, pits, holes, and areas that just don't look like the plaster was evenly applied. Most issues were noticeable immediately after plaster. Some of the small holes now have dirt and debris down in them that will not come out. The pits and extra rough areas were like that as soon as they finished plaster. The steps and corner areas seem to be the worst with little holes and rough plaster. Then after a week long white streaks showed up down one side of the pool and not the other. And after a few weeks we have about 10 round rust looking stains on the walls. See some example pictures for all the issues I have questions about. There are quite a few other areas with holes, pits, rough plaster that I didn't attach a picture of too. I am wondering if any of theses issues are normal and typical in construction ? Or is this a poor plaster job? We have kept our water in balance and brushed the entire pool twice a day for 3 weeks. Also will acid washing correct the streaks ? That is the one thing the company has offered to fix...Acid wash to take care of the white streaks that are down an entire wall. Any advice you have about these issues and how to fix or just leave as is would be appreciated. We want a nice plaster job but don't want to be over the top complaining if any of this is just how plaster turns out. Thanks in advance for your help.

I just had my pool built in Aug and the rust spots showed up after we had a week of rain, but once the water was balanced, they went away and haven’t came back. I Have a couple of rough feeling plaster spots but you can’t visually notice them. We used a colored plaster and we do have some spots that have small dips throughout but they don’t stand out at all. All in all we are very happy with it and have had no complaints or anyone mentioning it when we have had people over.

That looks a little rough to me. Just don’t let too much time pass before you talk to the pool builder (if you feel it’s necessary). Doesn’t hurt to call them back.

I’m no expert but it looks like you got quite a bit of someone’s left over coloured pebbles to me. I’m assuming yours is meant to be pure white. Brushing has likely exposed more of them and also made several come loose, creating the pits.
