Hi I have a 5 year old Gunite/Plaster pool. We live in the NorthEast so our pool season is Jun to Sept.
During first 1-3 years the plaster survice seemed to get stained slighlty - During year #3 the surface became very rough - where your feet would be come sore after being in the pool for a little while. On opening the pool during year 4 - the plaster was very rough to the touch - our pool company suggested draining, sanding and acid wash - which we hestitantly did.
I never got a real sense from any one what caused this. I started using some products from Jack's magic to try and control and stop this from happening again - not sure if it is working or not.
Can any one share thoughts or suggestions
