I owned a home in Phx with inground pebble-tech (sp) for 8 years and loved it. I used a fairly new product, in the chlorine family, but much more stable and no smell. And less cost. anmd in 8 years no green pool. Actually everone commented on how clean you felt after getting out of the pool. Required 2 Xs per week attention in swimming season, 1 to 2 Xs per month in off season.
Make sure when you build the pool that you get a very good, and low noise motor and pump. And that they put in a cleaning port with a volume control for some kind of automatic cleaner like a gator. Gator cleaners move around the pool and clean as it filters. I would never be with-out one. If you have round edges between the walls and the bottom, some gators will even climb the wall and you will find you never have to brush. Mine would even get the "ring around the tub" pretty good and I did not have to brush much at all. And we used the pool every day in summer. I'll see if I can find the name of the stuff I used.
