I am getting a small amount of pebbles (maybe 2 teaspoons) in my robots filter basket when I rinse it out. I keep my chemistry pretty well balanced (see pool logs) and my CSI is kept kept slightly negative to keep my SWG from scaling. There are rough spots in the deep end of the pool, but they have been that way since the pool was filled and don't seem to be getting worse. Is getting the small amount of pebbles normal when using a robot or is there something I need to be doing with the water to better balancet it?

Since you say there are some rough patches since build, it's possible that the plaster crew was too aggressive with the acid wash and removed a bit too much plaster, leaving loose anchored aggregate. Any chance that is aggregate off your roof washing onto deck and blowing into pool?
Aggregate from the roof is a possibility. I will need to look at it more closely next time i clean the basket to see if it matches.
Pretty small. I would say on the order of what the Pebble tech or shingle aggregate size is. They did feel a bit sharp edged which has me leaning towards shingles not pebble tech now that i think about it. When i get home i will pull the robot and see what comes out and take a pic.
