You could get low light with a pair of Coralife or FishNeedIt 2 bulb T5HO lights, with one near the back and one near the front of the tank.
Thanks for the info. Since creating this post I did more reading on here and I'm thinking of using the "clamp lamp" cfl solution.
Given this new revelation, what I want to know now is, can I use three (3) clamp lamps using 15 watt bulbs at the front and keep the current light to the back? All lights will be placed directly over the tank and will not be hung above.
Would that give me an adequate amount of light.
