DIY led for 75 gallon

[Saltwatercoral2]

I am contemplating doing a DIY led build for my 75 gallon tank. How many leds would I need? Im guessing around 72. I will have lps, clams, anenomies, and softies. No sps at all. Thanks in advanced!

i plan on using 48 cree xp-e royal blues and 24 cree xp-g cool whites all with 65 deg optics the xp-e will be driven by 2 eln-60 48d with 2 parllel stirings of 12 on each driver and the xp-g will be driven by 1 eln-60-48d with 2 stings of 12 ran in parallel
I plan on using this setup up on both my 75 gal sps dominated reef and my 125 tall softie/anenomie reef
