MH Bulb Question

[TJDeMars]

I need to replace my MH bulbs, my question is on color tempurature(k). I currently have 3-150 watt HQI's at 10k. I would like a more blue/white light. The original bulbs are Corallifes' and they seem kind of yellow and always have. Would 20k be too much blue, or would a 14k be better? The light also has 4-96 watt actinic PCs which are also in need of replacing, those will get actinic 03's.

IMO 14K would be best with the 03 supplements. 20K would be too much blue.

With a 20 k bulb do you need another light to give off white light?
