We have a problem and need help

by Mike Wells
(Flowery Branch, GA)

we built a pool in our yard, paid a lot for it, has a lot of flagstone, wall above and below, fireplace, ...; the problem is that we have a flagstone waterline and flagstone coping around the pool that are losing there color, graying out and bleaching out. the pool is saltwater, we live in Georgia and get a lot of hot sun. what can we do to restore, revitalize and then deal and protect the stone. we have listened to some who thought that knew and i think that is part of the problem. i am willing to lower the water level and add color back to the rock on the waterline - like we add color to the waterfall each year, but when i do i want to seal it in a way that will protect the color and the rock. i am willing to clean the coping and add color if necessary with whatever it takes, and then i want to seal it the same way. if i can clean without soap based products, it would help a lot, else i will surely experience and algea bloom, but if i have to deal with that i will. what i need is someone who can tell me what to do - for sure - and then i'll do it.
thanks
