The tank is 4x2x1 (60 gallons) and we have two 42 inch 40 watts tubes (One growlux and one high power show-off-your-fish light.) From the sound of it we might need brighter light. Unfortunately we can't fit any more tubes in the hood.
Am heading to our local Aquatic Specialist this weekend. (Can't wait!) Thank you all for replying so quickly. You've given some really helpful advice. I will keep you posted.
