Just another opinion on additives. Wait on them. Water changes should supply anything you need for a long time. I've never dosed Iodine, ever. I only started dosing phyto because I have clams. Feather dusters have always done just fine without it.
Water changes and skimming will be your friend for a few months. I'm a huge fan of water changes, but some aren't, especially during the cycling. I prefer to export as much of the "junk" as possible, and water changes are the way to do that. Some feel this hinders the cycle. I dunno, it worked for me, perfectly.
A cycle should take about 6 weeks, technically. However, I'd wait at least a couple months before adding corals. Near the end of the cycle, you can start thinking about a cleaning crew (snails, hermit crabs), and that will also help. At about the six month mark, you should really start feeling confident about your tank, and at about a year, "Bob's your uncle", it should be very well matured and husbandry will come naturally.
I'm not a fan of using fish to cycle a tank. I added my first fish about 3-4 months into the game, and my first corals just about that time, as well. The tank was filled with just the cleaning crew until then. As a point of reference, in the beginning, I had about 60 snails of various species and about 40 hermits in my 38g. A couple years later, that number is drastically lower, but so is the nutrient load.
A new tank is so fun, and full of all sorts of adventures! You'll see all sorts of "WHAT THE HECK IS THAT THING" types of animals in the middle of the night. You'll watch the maturation step by step. It makes me want to set up another tank!
When I first got into the hobby, I wanted to see photos of month by month as a tank matured. So... I did them myself. Here's a small gallery of full tank shots, periodically through my tanks 2 years.
