You show coralline algae on the glass so light can’t that that far out.
You don’t get to have any input on where your nems go. They will move until happy, so set the light for corals. It may take time but for every change you make, stuff will have to get used to it…..just leave them.
From a general view, 250-300 par top, 150-175 par mid, and 80-100 par bottom are reasonable if you can measure par.
Without knowing, it’s always better to underlight rather than over. Start where you are and increase 5% monthly and watch what corals are doing. Do they look full at peak period?
