I currently am working on the lighting issue as well. We just purchased the 36" 3x 150w with T5 actinics http://www.championlighting.com/prod...cat=629&page=1
My tank is 125 gal
6' long. I have the lights in next to my 2x96 watt 36" power compacts and I just can't decide which actinic lighting I like better, the power compacts gives off a more purple glow and the T5's is a bright blue. We have finally decided to go with the T5's because of bulb life and the bulbs are much less expensive. This website above has the cheapest price we could find and we ordered Wednesday and got the lights on Friday with ground shipping that is free. They have a 10% discount for this weekend!!
