I am trying to research the best new upgrade lighting for my 150 gallon reef.The tank is 6ft long. Right now I have 4 65 watt powercompacts bulbs and 4 96 watt power compacts bulbs on the tank. They generate lots of heat along with the chiller in the late spring and summer... Hubby likes to complain about it, so for sanity and energy costs I'm looking for a green and good alternative to upgrade to. The tank houses these items, excuse any spelling mistakes, hynofora, pagoda cup, trumpet coral, Bta's, zoo's, mushrooms, button poylups,candy coral,leathers, I think thats most of them... :roll:
