All lenses on @15" above water line (except red and green lenses)

Massively surprised by these results!!
Looks about right. When I pulled my lenses my par dropped by about 60-70% at 16", I dropped the lights to 8" off the water. Now with 100/100 (swapped LEDs on white channel) I get 794par at surface
Now more of a usable level, 50/40 I get mid 300par 6" under the surface and around 140 at the bottom.
At 75/60 which will likely be my top end once I move to more SPS, is roughly low 410-435par 6" below the surface.
