10K, 14K or 20K Metal Halide

[strager]

I am planning to buy a metal halide lamp. Which one is good for coral 10K, 14K or 20K?
How about this lighting:
1 X 150 WATT METAL HQI HALIDE HQI 20,000K BULB
2 X 39WATT T5 10000k BULBS
Thanks.

im not really sure which on of those lamps are better. I have heard that 10k MH bulbs are better for corals but the other bulbs will be fine. I have a 10k bulb and its pretty yellow/white. When I need to get a new bulb im probably going to get a 14k

I had a 20K bulb and changed to a 10k bulb and my corals are doing so much better under the 10k bulb, that being said I would not mind trying a 14k bulb just to see what would happen.

10K is more intense. 20K looks bluer/nicer.
I would reverse that setup and go 10K on the MH and Actinic or 50/50 on the T5s.
