    I currently run the 20K BLV Nepturion 250W SE bulb over my tank. Couple of months ago I used to run the 14.5K Gisemann bulb. I have measured PAR from both and obviously the 20K bulb has less ( about 100) PAR when compared to the 14.5K bulb. Not too concerned about PAR, but I think growth is...

    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.
