    Geisemann Futura vs Illumagic Blaze

    Doss anyone have any experience with these two lights? I’m trying to decide between the two for my new tank build (120gal 48x24x24). Geisemann obviously is the bigger name, but I don’t see any uv diodes in the clusters. Illumagic is lesser known, at least around the Midwest where I live, but...

    T5 4 bulb par?

    Anyon have a 36" 4 bulb t5 over your reef and happen to have a par meter? I have one 8" over a 40b and was wondering w/o the investment what the #'s are. My rocks are pretty low so probably about 14" from the rocks to the light.

    Talk Me Into Or Out Of Halides
