Which colour spectrum?

I have a 20h nano and I was thinking of upgrading my lighting. I saw this fixture on sale and it fits my budget.

The only problem is, I have no idea which type of bulb to pick. I have a choice between a 20k or a 10k de bulb. I was thinking of getting mostly LPS with a few SPS and a few soft corals for my tank. Anyone have any idea which to pick?

Thanks,

Oh, one more thing. Does anyone have any experience with these ARC DE bulbs?

Thanks,

20K definitely ! Better colors and no need for actinics

20k is Blue
the 10k is white

Would the 20k light have enough PAR to give good growth for my LPS and SPS corals?

Thanks,

on a tank of your size it should..if you're really concerned about it, get the 10k

Alright, I guess I will go with the 20k bulb. Thank you all for your advice.

Don't forget that you will also need to budget for a UV sheilded reflector to house the bulb and sockets.
