Replastered pool with dark grey color about 1 year ago. Using TFPC method. In November CH was at 800 and PH went high for about a week and resulted in calcium stains that a very noticeable. I am considering having an acid wash on 1 year old plaster to remove stains.
Will acid wash remove all calcium stains?
What affect will this have on dark plaster?
Will this cause any long term damage to pool finish?
Here are my water readings:
