You’re not going to need 100% intensity unless you’re going to frag sps every weekend lol. Can’t see full picture but that tank looks small like the scape goes end to end top to bottom. If so you’re going to have no where to place new low light corals, plates, fungi etc. also going to have a lot of dead spot issues. Should leave some room and tighten up or remove a rock leaving some room on one end or both for rubble and frags later.
Now to address lighting.. 100% intensity is going to fry most of what goes into that tank at the beginning plus going to be really good at growing algae lol.
I would recommend the following.. depending on what the setup will be..
Notice this is 30-40% recommended intensity at these settings in beginning (when corals start going in to tank should be even lower before then.
These are what come from factory for raidon lights as was determined after a lot of research they did on lighting years ago with coral labs. You speak to any experienced reefer with show quality tanks and they will tell you that it’s next to impossible to improve upon these settings.
I run this lps setup currently at about 60% intensity with a much less powerful light then yours giving me par of 125 in middle range 50 at corners on bottom and still peaking at 450 top middle so I could grow some sps if I wanted..
Rule of thumb.. underlighting your tank a little will slow growth but over lighting your tank a little will kill everything. It’s always best to start low and slowly build up intensity over time till the corals tell you it’s too much by bleaching then turn it back down a few ticks.
I’d personally start at the 30% range suggested with that string of light. Maybe 35% as I think the testing was done with light 12” above if I remember right and you’re a little higher then that.
