I run a six bulb ebay fixture, bulbs are catalina 12000k x2 and 4 catalina actinics, so far so good! Currently have no problems with high level light corals, havent tried a nem yet, waiting till june. Im going to be buying ati bulbs probably with the same setup u have. My fixture is only 36 inch with 10 lunar leds as well totals of 234 w over a 35 gallon with a footprint of 3 square feet
