Ok I have a 30 gallon tank....lol thought it was a 40 or thats what i was told when I got it.either way. I'm getting a 4x39w t5 from a buddy. its new and never been used he said it has 4x 6500k and 3 moonlight led's. I am doing corals so what bulbs do I need to stick in this thing to get some growth. I also have a singlebright led that puts out 600 lumens that I may try to squeeze in there with the t5's. so again what bulbs should i go with. is this going to be good light for corals and will I have enough light to slip in a clam the tank is 16'' deep
