RIght now I have a FOWLR, but I am slowly upgrading to reef. I have two lighting choices. My lighting right now is 3 regular strip lights with special bulbs, Two are 9325k saltwater lights and one is a 20000K atinic bulb. what I was thinking was adding a 65 watt Power Compact lighting house. That would be a total of 125 watts. I'm thinking of raising Pulsing xenia, green polyps, maybe a brain, and mostly softies. My other lighting choice was a 175 watt metal halide with a 10,000K bulb, from hellolihgts.com, pulse start. I would also have the regular strip light flourescent on it to give it a bluer look. I just was thinking that that would be overkill since I am not going to keep SPS or anything that needs that extreme of lighting. If I were to go SPS I would probably go SPS in a couple years, not now. And if I had the first lighting system I could always add a 75 or 100 watt metal halide to it. Also If I were to get the metal halide 175 watt, should I get the 10,000K bulb or a 20,000K blub?, thanks.
