Hi, we are getting estimates to Diamond Brite our pool and one person stated that if we went with a color that was not standard and dye was used, there is a possibility of it fading because of chlorine. When I called the company that supplies the Diamond Brite, they said it is not dye but a different pigment (which seems like a dye to me). I was curious on anyone's thoughts. I have heard that it may be a good idea to switch to a saltwater pool to prevent the fading. Thanks in advance
