In over my head???

I'm not aware of ever seeing a discussion on this topic here.

You might want to post on PoolSpaForum.com; they have a lot more builders and installers then we do. But if you get it installed, I'd recommend you come back here for water treatment info -- they tend to be very old-school and like to promote brand-name ($$$'s) patent medicine type products.
