New to Saltwater - So Many Questions!

[River]

Wow, thanks all for the responses - wasn't really expecting that! Good to know about the ph. I do have a skimmer but it's not running yet. I did a dumb right off the bat and need to wait until after a water change or two to get it going. (Ran out of ro water and figured a couple gallons of tap water wouldn't hurt. Stress Coat did though. Won't be making that mistake again!)

I'm just headed to work though, so I'll put up a better reply on my break. Just wanted to say thanks in the meantime!
