Read Hoppys thread as noted above. It is a very good and helpful thread!
T5HO are great bulbs but don't over do it. Watt/gallon rule goes out the window. Other factors are in play with these lights (most importantly; height of light from surface of water, depth from surface of water to surface of substrate and quality of reflectors). 2 of these lights on this tank would likely give you high light.
