Hello,
I want to upgrade my current light situation and wanted to try Metal Halides. I would like to use the Giesemann megachrome Crystal 17,500k Single Ended bulb with the Lumen Bright Mini Metal Halide Reflector. I am unsure what ballast to use. i understand that radium bulbs really require the m135. Does the same apply to giesemann? Any help would be greatly appreciated. Also would I need two 400 Watts over a 36" L x 18.5" D by 30" H tank? I plan to utilize them 16" from the surface of the water.
