Hi BS;

You might want to look at Ben Choi's site, www.howibuiltmyownpool.com

He build a pool himself after being active here for a year or so, and then started the website. The site is not actively maintained any more, but he kept meticulous records which you might find informative. He's also in the SW - Arizona - though I forget which city.

You've obviously thought about your pool from a technical view point; I'd encourage you to think about it from a user's point of view. For example, dark pools can look very dramatic, but will be significantly hotter. When I painted the pool the Camp Adahi Girl Scout camp on Lookout Mountain a dark "Viking Blue", the temperatures increased 4 - 7 degrees. That was a good thing, up there in that shady location. But if you are in, say, Phoenix you'll be gaining more like 6 - 10 degrees . . . and you may not want to have 100 degree pool in July!

That's just a start . . .

Ben
