hello, i am building an LED lighting fixture for my 75 gallon (4 foot) tank. in is 18 inch tall and the light will be 8-9 inches off the tank. i will be using 3w bulbs and i will be using half Cool white and half Royal blue. I'm not sure how many i should put though. i was thinking 28 (14 each color), but is that enough, or is it too much. i don't want to be limited to what i can put. i want to eventually be able to keep clams
thank you
