SPS corals grow faster under 10KK bulbs.
U can consider 14KK, it looks more white with a tint of blue.

it applies not only for sps but for all corals... lower kelvins will result in higher growth rate.. 6500k even better.. but very yellow lah....

i think 14k will be good... as Maculosus suggested
