I live in South Florida, have an older 15x30 in ground pool (about 30 years old) with brick coping (seems to be ordinary rectangular red brick) and Kool deck on the rest of the patio. The pump is the same age jacuzzi. I'm considering salt and looking for opinions on how this material and equipment might hold up. I've tested the salt content for grins and it's already at 2000 PPM from just using liquid chlorine over the years. Any opinions?
