Id be curious to see comparisions of the frags you guys have shown in different placements. For example if the armor of gods are in the sand bed, what would it look like if you had a extra frag and were able to put it up high.
I have some pink and golds and under low light are not very nice, but under high light look amazing. I have a 6 bulb t5 fixture and my tank is 12" deep.
