DIY LED advice needed for three tanks

I am in the planning stage for a new setup in my soon-to-be-built man cave.
I am going to have a 350 FOWLR (96x36x24), a 180 SPS dominated mixed reef (72x24x24) and a 100 fuge (60x18x20). I am planning to light all of these with LEDs.
I have been out of the circuit for a while and have been reading LED threads until my eyes water. Is there a formula to figure out approximately how many of what type LEDs I will need? Hint - I like a lot of blue - 14k-20k.
I want to go ahead and get started on some of this ahead of time.
Thanks!
