DIY 72 LED build

Almost seems these leds would put out way too much light if I have them at max.

Yes, way too much probably.

72 x 3w = 216 watts

My entire 165g has only 280 watts at max and even with the whites at 70%, it was too much for many of my LPS. Now blues at max and whites are just barely on and it gives the tank a 15000-20000k look and the corals are loving it.

I would reduce your whites and max your blues to help make your corals pop and not light-stress them when you change the lights over. Just my experience.

I think you have the correct # of leds but the wrong ratio of blue & white, the par is about the same except we see the whites as brighter, the corals just see the par.
I have 72 3w on my 90g, I run the blues @ 100% at 1amp (48) and the whites @ 85% at 1.3amp (24), it's @ 20,000K I think.
