Lighting question for a 75 gal tank.

Keith A · 03/29/2008, 11:32 PM

I currently have a 75 gal tank (48"x18"x21") and am thinking about upgrading to MH. I found a 400 wt, 10,000K MH light on the internet. Would one be enough or would I need two??? Right now I only have soft corals (nothing that requires a lot of light) but I would like to expand my collection. I've also been looking at LED moon lights. What's the difference between moon lights and actinics???

Thanks,
Keith

One bulb won't give you enough coverage for a 75, and an 400 watt one would be overkill. I personally have 2 *250 ( DE ) over my 75, with 2 *54 T5 for actinics.

Moon lights are mainly for a little light over the tank when all the other lights are off. The halides ( and actinics for that matter ) would wash them out.
