Thanks all...the pool builder came by and we talked about the startup. They use their own private labeled stuff after plastering going by the brand of Jack's Magic. I don't think they do an acid startup, but they said I only need to use this stuff. They say it is a sequestrant to prevent scaling and aide the curing process. I was looking at Startup-Tec, but wonder if they would let me use something else given warranty issues. They also told me to fill the pool right away, but I though pebble products need a little bit of air drying before filling. They told me they would do a light acid wash to expose the aggregate after troweling everything. I'll have to do some more research on the approaches, but appreciate any feedback. Thanks.
