So, my PB came back today and they sanded down my coping and did some powerwashing to clean up. They're finally done!! 
BUT, now my pool has a bunch of white limestone powder all throughout it. I can't even see the bottom in fact.
My PB told me he would try to come back tomorrow or next week and vacuum it, and I was like F that, I will just do this myself vs. waiting..
SO....
I know I hook the vac into the hole in the skimmer. I have vac'd once before so I know how it works..
BUT MY QUESTION IS... Is the vac going to push this stuff around and scratch up the plaster?? When I vac'd before, it was a little sand that my daughter accidentally tracked onto the swim ledge, and I noticed after vacuuming there was some minor scratches where roughly I had vac'd.
The scratches were very fine, like a pencil point, and are hard to see but are much lighter in color compared to the rest of the plaster. I have medium gray plaster so perhaps it shows up more with this color???
So before I go scratching the Crud out of my plaster further, I wanted to make sure this was a smart thing to do or to see if there was some other way to get sand/stone debris (power that has settled to the bottom) out of my pool!

Thanks!
