That's an extremely poor showing for the lights… ouch! With the amount you'd invested in them I feel for you!

I have been struggling with coloration ever since I set them up 5 months ago.
I finally got my hands on a PAR meter today and I think I found my issue. I am getting just under 200 PAR at 8" bellow the surface. We all know that is not enough intensity for SPS.
I am currently using the following settings:
100% High Output mode.
60% Blue
100% Royal Blue
100% Blue white
0% Cool White
30% Natural White
30% Sky White
50% Red
0% Green
100% UV
I can achieve more PAR from these lights but then the color temp looks too yellow. We decided to take them down. We will be experimenting with different types of metal halide fixtures for our SPS system.
