I have a 48 x 24 x 12 frag tank that is all sps frags and mini colonies. I was running a 400w radiums over the tank but have now switched to the sunpower. I have a bulb combo 5 blue+, 2 coral+ and 1 purple+ for now. I had a aquablue special but i swapped it out for the 5th bue+. I am wanting to know what is a good height to hang the light (distance from top of tank to light)? Thanks
