I don’t see anything.
Here is the Red Sea link to the specific lights and the size of tank and the presets. Just choose one of the three (it’s a choice on how white or blue you like tank to look). Do not alter the settings other then putting in acclimation mode for 14 days since you just got a big order of corals. After the 14 days, you leave alone. I never touched mine in 7 months and had nice growth, no burning, no too little light. The whole point of these restrictive lights was to setup success for a reefer and control so they didn’t mess up.

Now, with all that said, you have to do the research on what corals go where from sandbed to top of water. How big a corals tentacles are and how aggressive they are. And similar corals don’t necessarily go next to each other - I.e, Goniporas.
I know you’ve watched the Than videos, but you might need to do a deeper dive with his catalog. Also, the old ReefBuilders articles and videos from when Jake Adam’s was still alive are a wealth of knowledge. And Andrew Sandler just started his University 101 and it takes you through everything- especially fish. I am watching those and he goes into great detail that a non-science person can understand.
I’m sure the Smorg fam can recommend a lot more for you to read/watch.
Unfortunately this hobby is not a read once and your done. Especially since you chose a mixed reef like I did. Much harder for a newbie. And even though you are expert lvl in freshwater, corals are a whole different ballgame.
also, it’s,critical to have a,”database” that you can go back to anytime.
