Our new pool has had water for approx 30 days. Just a couple of day’s ago dark “rings” appeared in the deep end of the pool. We have stonescapes mini pebble Tahoe blue. We have been brushing it as suggested by the plaster company. We spoke to our pool builder and he stated they are hydration rings due to water under our pool and they will fade with time. He stated that replastering will not help. We are concerned that these are not going to fade and will look crummy forever. Any insight would be greatly appreciated.

Our pool finish is almost a year old and we have a similar "amoeba" shaped ring in the shallow end of our pool. We've only started to notice it over the last couple of months. We used Quartzscapes Grenadine Grey. I'm curious if anyone has thoughts on this too.
