Welcome back.
Looks like you're off to a nice (re)start.
By your tone I believe you appreciate any help you can get, so here's a Reefkeeping Tip:
LED light is extremely bright in a way our eyes cannot see. I can post some pics to illustrate this if you're interested. To avoid sunburning the animals, I would raise that fixture 5-10 inches. This will also illuminate the sides that, right now, are noticeably dark in that pic.
You may already know this, but "light acclimation" for coral involves using the dimming knobs on that black box LED fixture. Start at about 10% power and raise it ~5% every week, all the while watching the coral for delayed signs of stress. Also, placing coral on the sand and moving them up step by step is another way to acclimate them to the light.
Snails, snails and snails. Don't forget the herbivores to keep the display free of nuisance algae. Other tips are in the link in my sig line.
Aloha,
Mark
