metal halide lighting?

carnavor · 07/14/2007, 02:22 PM

im looking into changing from vho to vho metal halide mix, im a long time vho user. this is what i have in mind, four 250 watt 20,000k with four six foot actinic vho bulbs which will be dimmed by a solar dimmer on start up in morring and at night .
my 180 tank has soft corals, lps corals and two anemones. i want to add some sps corals after my lighting upgrade.
any feed back please.

thx joe

Seems like a lot of lighting, and a lot of blue to me. You should need four VHO actinic tubes if running all 20k bulbs, and honestly I think you can do fine with 3x250w. I am mainly concerned with how much heat you will be pumping out.
