I currently have Odyssea T5 Dual 48" 6500K Aquarium Lights 108W on my 55g and I was wondering if I could just add another one of those or something else to heighten the power of the lights? I don't want to overkill the lighting on the tank. Just enough to grow some swords, crypts, vals, and moss. Possibly rotala and/or dwarf sag.
