We were told the same thing, because it is filled the next day after plaster and acid wash. We weren't allowed to go in the pool for about 3 days.

Our PB told us to just wait until there was a couple of feet in the deep end to dilute and possible residual acid left from the wash. They use the same acid as we add to the water for the SWG. We swam in the deep end all afternoon while it filled. Our supervisor said that he even has seen people sit in their lawn chairs in the shallow end while the water fills up and their kids play in the deep end. I guess I would take the advice of your PB though. I wouldn't want to void any warranties.

Follow your PB's advice. The acid is not dilute enough yet, and you don't want to damage the Pebbletec and void the warranty. You can wait a few days, hard as it may be!
