So I am going to start my 60 gallon planted tank soon and was wondering what light fixture would be best. The dimensions are 48"L X 13"W X 20"H. I was considering the getting two 48" aquaticlife T5HO 2 bulb fixture (I want light to be evenly distributed in the front and the back of my tank). Here's the link for that: http://www.thatpetplace.com/aquaticlife-dual-lamp-t5-ho-freshwater-light-48in?sc=10&category=2789 I was wondering if two of them would be enough or if there is something better to consider. Any advice on what fixture would work best with the depth of my tank? I will also be running CO2.
