The PRO (not BLUE) Ill turrn up the cool white
What I meant was turn ALL the light up to 100%. and the slider on the left to 100% (which would be the MAX) light output. Then you can adjust the sliders, etc - IMHO there is nothign magic about the AB setting.

I think your numbers are about right. I have 2 Gen 15 blues on my frag tank. Its 12" deep and 24x36. My new goal with my frag tank is to grow all my sps on the bottom of aquarium on my plates instead of building up something to place them on. With the 2 Gen5 xr15's at 100% I get about 230 PAR in the middle of aquarium and 200 on the edges at 12" deep.

I have apogee 520. As OP stated. Documentation states immersion factor for say the 510 and 520 has already been enabled so nothing to do but read the number. I use the standard radion aquarium mount for mine. So they are at recommended height. At mid level at 6" I think I would have not issues getting 300 to 350 par range. But for me with no rock work its not an option.

I think I will go with 2 XR30's to get the PAR In need instead of trying 3 XR15s

Just remember these lights are only 100w, which by itself isn't much. Now when people stack multiple lights together that's when the PAR increases. If only wanting one fixture with one puck you'll need the Reefi Uno or Kessil A500 to put out a lot of PAR at those tanks depths and mounting heights. I know this is a moot point...

It's not a moot point to me, thanks for making it. I have 2 XR15 blues mounted over a 30x20x16 tank. I learned a lot about their PAR output in this thread and your comment about having multiples.
