Hello, we just had our new pool plastered on July 31st. We have been brushing the pool religiously as recommended. Tonight I was looking near the main drains and saw what appears to be an area of plaster that is rough and pitted. I haven't dived down to the bottom of the pool to feel it yet, but when lightly dragging the end of the skimmer pole over the area it appears to catch. There is also discoloration which seems to be getting worse. Our pool startup tech tells us that this is just efflorescence and can be cured with an acid treatment after the plaster has sufficiently cured for a few months. My gut instinct is that there is something wrong with this plaster in this area though. Any thoughts would be appreciated. I will dive down tomorrow morning to look at it up close. If those are indeed large pitted areas, is that a substandard issue that the plaster company should resolve?
