Oh, okay then disregard that last post. I wasn't aware of your situations.
Is this T8, T5NO, T5HO, etc?

As you can see from the second chart, a 2 bulb T5HO fixture is going to be medium to high light depending on the distance from the substrate. Since 55g's are 21" tall, use the 20" row on the chart. This shows you that if you have it on top of the tank or 4" away you will have high light. If you have the bulbs a foot from the top of the tank you get medium light. This is where things get iffy if you don't want to worry about CO2 and dosing ferts. Hopefully somebody else with more T5HO experience will chime in.
I wish my lfs did that! Good luck!!!
