i have a 180 with 3 halides and i am upgrading to 400 watt lights and there is an advertisement that say over a 6 foot tank i would be able to use two lights rather than three any thoughts on this? "The nature of the design will allow the typical hobbiest with a six foot tank to burn two lamps and get uniform light distribution over the entire length of the aquarium."
