ATI 8 Bulb 48" Dimmable Sunpower Fixture Par Reading With Seneye?

[Fanuc12]

Trying to understand the par readings I'm getting with with the seneye. i have the fixture 11" above the waters surface running 4 coral plus and 4 blue plus bulbs. Tank is 75 gallon 48"x24x18. Measuring at the surface I'm getting around 600par. At the bottom I'm getting around 235 par. I'm only running the fixture at 50% on both channels. I've seen post about people running these fixtures at 100%. I have contacted ATI and they say 100% is common. i would think 100% would be way to much par for the tank? unless the seneye is not giving accurate readings.
Anybody using this fixture over a similar tank for sps?
Thanks

PAR is just part of the whole deal. It's going to be basically impossible to toast your corals with T5s unless you shock them really bad, not properly acclimating them. Try "read" more your corals and let go those PAR numbers.
T5s are the safest way to lit your aquarium.

Yea I dont think those numbers are right at all.
On my 120 I never checked par and I ran 4b+ & 4c+ 4" off the surface for 15 months with great growth and no issues before I switched to halides.

Very close to the water surface here as well... never had any issues!
All at 100% when I was using the dimmable ATI for many years.
