I'm setting up a 40g breeder in my classroom, also getting back into reefing after a 5 year hiatus. Can you give me more details about the rapidled lighting? How many and what kind of LEDs? How high are the LEDs suspended from the tank? Etc? I like the look, and I'm thinking of going the same route, but I really don't know anything about LED technology. I had 4x55w pc retrofit kit over the tank last, and would love to use the same hood if I can. Thanks!
