I was thinking about changing from Metal Halide to T5 HO Lighting on my tank. I currently have 2-250 Watt Phoenix 14K Halides and a double 28 watt T5 Strip. The Problem I am having is that I get excessive heat build up due to the Halides even though I have 3 Fans in the hood. The other is my Electric bill! With Winter approaching it wont be as bad, But I want to plan this out ahead of next summer. If I dont go with a T5 setup, I will have to invest in a Chiller which would cost me money in electric. How many of you use strictly T5 lighting and have good coral growth? I love the way the Halides look on the water, But could give it up if the t5s worked as well. I have a 125 Gallon reef that is 48 wide. Below is a link of the T5 HO light system I was looking at. Has anyone used this? Is it any good for coral growth? Thanks, Gary
