I would really love to upgrade my lighting so I can start housing some soft corals. Currently I just have a standard 15W. The only problem is I hardly see any fixtures and blubs for my 10G. Its about 18-20" long. I did see one fixture/bulb, but its $160 dollars (for 96W). I was hoping to find something a bit cheaper. Can anyone provide me with a specific model that I might be able to order online and a link to it?
