hmm, from what i understood in that post (technical stuff > me) it didnt have enough lighting in his tank, but i dont have metal halides or another tank with better lighting to put it in, it was kinda in the shade under a rock, i put it on the top directly under the light .... not sure what else to do
edit: oh, my tank has orbits compact "2X96W (1) 96w Dual Daylight and (1) 96w Dual Actinic" in a 46g tank
