After a long wait, our builder finally poured gunite this week in North Texas. We have been watering multiple times a day in the heat. ( sometimes 6 -7 times.) In the mornings, one part of the pool ( where were having water before the pool went in ) in a corner near our steps will still be slightly damp, but is leaching some milky whitish substance. Any thing to be concerned about? We are doing mini pebbles, I assume that it won't leach through them?
