    Okay I ordered this fixture off bigal's Nova Extreme High Output T5 Lighting Fixtures

    said it came with 10k bulbs but instead it came with 12kk. I have always used 10k for coral growth. What is the difference? Which is better? the description also says it comes with moonlights but there isn't anything extra besides the four bulbs. Aren't moonlight normally a few LED's? Does anyone else use this fixture? THanks

    The 12000K have a little more blue light. You will most likely see no difference in growth and possibly a little better color. You are right about the moonlights. Can't help on the fixture.
