Thanks for the info, but it does not tell us much. Can you tell us who manufactures the bulb and the fixture please. Any other relevant details would also be nice, such as bulb temp, in K, as well as CRI, wattage, and tank size, only if known.
Yes, many people here have used halides or are using halides. I had 3 on my 125 and 2 on my 120. Along with halides comes CO2 (usually) and increase in ferts (also usually). personally, I thought they were great to have, but now I have swtched to PCs due to the "look" that I wanted in my family room.
