I'm looking at MH lighting for a 60"L x 17"W x 16"T.It's only 16" tall because 6" DSB.I want to keep a bubble tip and maybe a place to grow out a few frags (soft & sps)
I'd do a pair of 250's w/ actinics, 175's should be sufficient too since the tank is so shallow. I think a 60" tank isn't long enough for a third halide but i could be wrong. Make sure the bubble tip is in there waaaaayyy before you start dropping frags in there. Murphey's law states that if you put in the anemone later he will walk all over your frags making nice white FO decorations.
BTW, Dr. Mac has some tank raised E. Quadricolor's, go captive raised!
