Welcome to the forum! Great reef tank you've got going. Your marine experience will come in handy on this side of the hobby.
Looks like you're off to a great start.
A couple things you won't really have to worry about in this realm: phosphates, GFO, carbon.
Once your Brightwell ferts run out, you may want to explore buying dry ferts online. Probably a trillion (okay, a bit of an exaggeration) more bang for your buck. Since you're experienced with coral, dosing EI should be easy to grasp.
Can't wait to see how it all turns out.
