Lights

[MSB123]

What I have:
50 Inch Reefbreeders
61 inch AL T5 hybrid fixture
2 actinic bulbs
2 blue Plus bulbs

The issue.
The tank is 72 inches long.
The T5 fixture is 61 inches long, and the main LEDs are only 50 inches long.
Here is the plan.
Black is tank
Yellow is rock
Blue is T5
Red is LED


I want acros where the rock is. Will this be enough to grow them? Will there be visible light drop off at the end of the tank? (Where there is no rock)
If so, how should I fix this? (Not planning to grow coral there, but I do not want visible light drop off. )

I think we all be making guesses here unless a par meter is used. Too many variables that can’t be accounted for. I need one myself as I really have no idea what I’m current getting
