Hey, where can you get that canopy with 10000K lamps? I thought it came with 20000K lamps.
I didn't notice any photosynthesis in my tank when I had my actinics on. I measured the O2 levels in my tank and it did not rise when I had only my actinics on. I would never buy Actinics again. For supplementation, I would use 55W GE 9325K PC because it offers usable light and produces more vivid colors to my eyes and camera. My MH are nice and white but to bring out the purples and reds and blues and greens, etc, that PC bulb does it for me.
Check this out. Its hard to believe but they are the same tank with different bulbs:

To me, your MH is your main source of light already. So now, all you need in your supplementation is to make your tank look vivid. Unless of course, you'd rather have a blue tank.
