Welcome to CanReef.
All great advise
The most important thing though, "Take it nice and slow", patience is a virtue. Will save you a h*ll of a lot of money too.
I converted my first tank from Fresh to Salt a few years back, and never looked back. I just added salt to my current water and ran it for a month. Didn't take too much scrubbing, as most of the algae died off anyhow.
Drop by anytime to the store, and we'd be happy to answer any questions you may have too.
