Hi, I am thinking of re-doing my pool and giving it a new inside finish. I am told that River Rok is better than Diamond Brite. My pool was done in Diamond Brite Cool Blue about 15 years ago and some plastering is coming off. The water is a bit cool and would prefer a darker colour to be honest. I was considering doing using the River Rok finish (unless someone has a better recommendation), and wanted to know what people think? It would be helpful to get a few examples of the finishes that River Rok offers to see how the water looks with the different colours they offer. Thanks very much!
