VHO Lighting Questions

[Beverly]

Troy,

What do you like better about the Coralife's 1000k VHO tubes over URI's 10000K tubes? I'm looking to increase the colour of the corals in the tank. With the URIs, most of the corals are brownish in colour.

For example, I have a Euphyllia sp. It was under a 175w ARC 14000k MH in my 37g and the colours were light green tips and pale green/whitish stalks. Under the two 10000k and two actinic VHO URIs in the 67g, the tips are still light green, but the stalks have turned light brown.
