George, you have run both 6500K and 10K lamps. For coral growth which do you prefer? Based on optimum coral growth and knowing my supplementation, which K of lamp would you choose?

IMO, IME, For coral growth, 6500K is better in my tank. The color might not look perfect for *human* if you run it alone. I think a pair of VHO actinic will be a perfect supplementation for the Iwasaki.
