First let me be clear, I'm not the chem person in our family.
When we bought our house the existing pool (20 years) had white plaster discolored to blue. I understood from the previous owners' pool guy that this was caused by the heater going bad and copper coming into the pool. The heater was fixed but of course the plaster stayed blue. During the last few years we've battled the green hair issues with my daughter and myself. We've recently discovered that this due to copper in the water chemistry that the copper is actually in the plaster and that it why even after fixing the heater, the copper remains.
We've recently completed a pool remodel and they are plastering/pebbling Wednesday. We are very excited but I wonder... Will this solve the copper issue? Does/can the new heater still hold copper? All of our equipment is relatively new - replaced prior to selling/us buying the house. Do we need to worry about the copper coming through the equipment lines or anything?
Might be silly questions - sorry if they are.
Thanks for the help.
