Im new to a Gunite salt water pool. We always had a fresh water liner pool. When we bought the home there were black areas of the gunite that simply wouldn't come clean even with a stainless bristle brush. I have been told its from the PH being too high. I don't know if there is a process to fix this in a faster fashion. We did bring the PH down and it seemed to slowly get better, but to be honest, not many people know anything about gunite and saltwater in my area so everyone is just throwing guesses at a solution.
Has anyone dealt with this before?
Thanks
