im ordering something on the big aution site....have a ?...the bulbs in my light are 12000K, and I can choose from 10000K(white daylight) , or 50/50 (1 tube 10000k, 1 tube actinic. I should order the 10000k bulb right? Will this effect anything since i have 12000K in there right now? Thanks

it will just be a difference in color, the 10000k will be more white than the 50/50. if its fowlr, id go for the 10000k, if its a reef id go for the 50/50, but thats just my preference.

actinics will bring out the "glow effect" in some corals.
