crazing in new concrete pool

[Bozer4]

Hello, we had a new concrete inground pool installed just 6 weeks ago and I noticed what I guess is called crazing on the shelf of the pool. I can't feel the crazing with my finger nails but does this have potential to become a bigger problem down the road? I haven't contacted builder yet, I wanted to get some
outside opinions first. Thanks for your help.

Looks like they let the plaster dry too quickly and the surface shrunk. May not be much you can do about it but I'd definitely call the PB and complain - that should not happen.

Yep, it was about 100 degrees the day of the plaster install which is typical for this area in the summer. It also took hours before the water level reached up to the top level of the pool where the shelf is located.
