Increasing Xr30 pro cool white doesn’t increase par per SQ-420X?

So in this pic I moved a pinky the bear colony to the aquarium bottom, front left.
The tank depth is 28” and 9” above the water is a G6 XR 30 pro. Using AB+ at full intensity it only reads 130 PAR using a SQ-420X meter.
Increasing the cool and warm white from 28% to 100% intensity doesn’t seem to boost the PAR. I know the SQ-420X supposedly isn’t full spectrum but I expected at least some increased PAR from boosting the whites.
The colony was doing well on the bottom at back left under a 400W radium MH at 220 PAR.
So I’m wondering if the XR30 pro would be sufficient light if I boosted the whites despite that not seeming to change the PAR values?

I'd be doing some testing with that PAR meter. That just doesn't seem right to me.

Did you change the software to detect the immersion effect? That is not a super accurate sensor, but it should still pick up some difference.

I didn’t know about the immersion option. That boosted the par about 10. Don’t know why, but now the par increases with cool white light about 20 par, another 5-10 with warm white, and about 5 more with green maxed out. I see there’s a high intensity lens for the xr30, thinking about getting that. Will run the cool white maxed out till then. Thanks for the help!
