Our plaster is about 4 years old. Recently we noticed that it is discolored in a number of places (only on the bottom, not on the sides or in the spa). The discoloration is dark and a The person that did the replastering claims it is because our CYA levels were too high. Does that make any sense or could it be something different?
 
CYA levels too high … hogwash. They gotta blame it on something.

Unfortunately, plaster is hand applied and mixed on site and color variations can develop.
