I have metal halide 10K bulbs and my tank is 30" deep. The light fixture is about 5 inches on top of the water. How far down/up should the acan be placed? Do they require alot of light?
what lighting did it come from?? i have mine under a 250 SE 10K, and it loves the light.. its about 20 inches from the MH.. if it came from lower lighting start it low and slightly shaded and slowly bring it out into the light and higher..HTH
