Hey Bubba, I apologize in advance if you've already answered this somewhere, but have you ever used a PAR meter on your frag tanks to see what kind of numbers you're getting? I have one right now that I rented from BRS to adjust my LEDs over my new frag system and I'm trying to adjust my lights. On my LED tank I'm pulling a bit over 300 PAR in the center and around 220 at the far edges. That's at the bottom of a 12" tank. My T5 tank is pulling a little less than that. I'm wanting to make my LED spectrum a little bluer, but I don't want to sacrifice too much par. That's why I rented the meter to make sure I'm finding the right balance of PAR and color.
