You are thinking along the right lines. Oh to be a newbie again. It sounds exciting when you have been keeping reef tanks for decades. I would add one thing to the water chemistry side of things. Buy an inexpensive doser rather than investing in Kalk stirers, or CA reactors. You will be able to adjust the amounts of the solutions that you use as your tank matures. CA, Mag, etc... levels are somewhat forgiving but an unstable Alkalinity is not. It is really important for many coral species. Stable Alk leads to a stable PH. IMO there is no easier way to stay on top of this. Another super important point that I didn't see addressed is Pests. It is far easier to prevent getting them than it is to eradicate them after you are infested. It is not uncommon for new reefers to buy a bunch of expensive corals, have some success and then notice 6 months or a year into the hobby that their tank is infested with some form of pest. It can be discouraging to say the least. Many new hobbiests just give up when faced with such challenges. Do your research regarding preventing the introduction of these pests. Dip, dip, dip. Quarantining new corals is a great idea too. If you are not lazy you will do well.
