So I finally got an MQ-510 to measure my par in a 10-gallon waterbox cube under my first Radion light an xr15 blue G5. Reading around on the forum when I was just eyeballing my lights (as I've always done) I read a lot of posts making it sound like it was super easy to fry my SPS with these lights so I played it safe and stuck to what seemed on the safe side of an eyeball estimate. I got my par meter today because I was suspicious based on color and growth the lights were too low. Sure enough at 80% overall intensity white red and green at 30% and the rest at 100% I was barely making low 200 par 6 inches under the water!? So I set 100% everything at 100% intensity and still don't hit over 400par anywhere in the tank that's over a couple of inches under water. What gives? The only thing I can figure is that there is so much light spill from it being over such a small tank.
