Wetedge Luna Quartz plaster was applied Monday. They acid washed it and then immediately began to fill it with water. It took about 36 hrs to fill the pool. Wednesday PB came by and started up pump and added whatever chemicals were needed. He noticed these black spots. They are luckily confined to one general area of the pool and appear right below tile line streaking down a few inches.
Anyone have any idea what this is?
PB notified Plaster Company and they are to come look at it today.
