Congratulations on the new pool! I'm sure the experts will chime in with what your first steps should be, probably adjust Ph and get bleach in it ASAP. I notice you have a Nature2 system on your list. That's a mineral based sanitizer, and you may want to read this before you decide to connect it to your new pool: http://www.poolsolutions.com/gd/mine...es-a-scam.html

Personally, I wouldn't use it. If you want something to help automate sanitizing, I'd look to a SWCG or chlorine feeder system (assuming your warranty with doughboy doesn't forbid salt that is).
