My current setup is 2 150W HQI bulbs in 20K and 2 96W actinic PC bulbs. Needles to say, the light is very blue. I'd like to warm my spectrum up a bit, but would like some advice on what people feel would be the best way to do so. I could swap my HQI bulbs out for 10K and leave the PC actinics, or I could swap my PCs for 10K units, or change the HQI to 10K and PCs to 50/50. I'm leaning towards changing the HQIs to 10K and leaving the PCs. It's a 24" deep tank, and everything is doing fine, but I feel they could be doing BETTER. I have mostly LPS with a few softies, but I'd really like to get a clam or two one day. I'm comfortable with their care, but I think I'm a bit low on lighting for a clam on the bottom of the tank.

So, what are peoples thoughts?

whats ur tank capacity?

Oops, it's a 120.

couple things..
first, i think you mean cool it off, not warm it up.. heating it would be even more blue.. ;) red/yellow is cooler..

anyway, that said i would change the MH out for 10K bulbs and leave the actinics.. thats JMO.. :)

I agree with rob. I really like the look of a strong 10k MH bulb backed with a actinic bulb. The 10k will bring out the strong "white" light and then the actinic will level it off to look amazing.

Hmmm........think again. :rolleyes:

Agreed.

Thanks for the advice. Technicaly, Rob is right. The higher the Kelvin number, the bluer the light, but I menat warmer colors, not temperature. It's just semantics. Thanks again for the input, that's what I was leaning towards anyway.
