Actinic lights and 6,700K lights

[Keith A]

I will be replacing my lights in the tank soon. I'm looking at getting 2 65 watt actinic PC bulbs and 2 6,700K PC bulbs. Would the actinics "drown out" the visual yellowish color you get from the 6,700 K? I'm trying to get the best lights for coral growth. I also have 2 250 watt 15,000K MH bulbs. Any feedback would be great.

Thanks

Its gonna look a little yellow based on my experience with a similar setup.

Too elaborate:

When the 2x65w 6700K and 2x65w Actinics are on, it looks a liitle yellow.

2x65w 6700K and 2x65w Actinics and 2x250w MH (hamilton 14k), looks bright white.

2x250 MH (hamilton 14K) and 2x65w actinics- a nice white-blue.

Go with 2 x 10K PC bulbs and 2 Actinic (or 420nm/460nm) combo bulbs. We tried the Dual daylight 6700K/10K Sunpaq's and they are too yellowish w/o actinics. With the 2 x 10K's (Sunpaq's) and their Dual Actinics you get a pretty much bluish-white light with a hint of purple from the 460nm... Good growth on plating coralline, leathers...
