I have a similar dimension tank with the same lights on it.
Having done extensive PAR measurements with the APEX PAR meter, I would suggest you need a 3rd light for corals.
It will provide much better overlapping fields of fire for the photons, decreasing shadowing and hot spots.
I like the aquascape, nice job.
Thanks [emoji3]
I was thinking about adding one more light but a smaller 15 instead on the middle.
As you mentioned there is a light gap in the middle
