These seem very low indeed. How high are the Radion hanging? What kind of measures do you get at the surface of the water? Is that with the glass cover on?

My XR30 Gen4 pro are at 9", and at 72% AB+ I get 200 PAR under 14" of water (on the sand)

Nice! Now you're getting somewhere! The first group of readings were definitely not enough to support much of any coral growth.

The 2nd group of readings still seem low for radions. I was getting 320 PAR with my kessil A360x. While I havent tested PAR yet, since I installed radions, coral growth and coloration has been significantly better than when I had under Kessils, which means they're that much stronger. It doesn't seem right that at 100% you're only getting 320 at your highest point.

How far below the water line is the top of your aquascape?

Regardless, you're well into the PAR zone for softies and LPS with the glass top off.
