Unfortunately it's plaster and hasn't even had time to cure. Your contractor has to bite the bullet on this one and redo it. How is he going to patch...

If you're lucky it's an isolated area. It can be repaired underwater by a diver. Cost should run about $250 to $350.

I'd be careful about setting a chlorine tab on the surface of your pebble finish. The acid of the tablet will leave a nice dark spot if left on too...

go heavily dyed gray to black plaster with black quartz

sounds like scale. add a sequestering agent. lower and maintain ph to 7 (6.8 may be required if 7 isn't enough after 3 days) and brush pool twice a...

I have used vitamin C tablets on rust stains and it seems to work well.
