I ran 50% blue and 15% white when I had a 16" extreme over my frag tank. Unfortunately it has huge hot spots even when mounted 14" above the tank so I went a different route. I'm going to eventually use it on a coral quarantine tank

i just pulled the center circle of lights...Pulling the lenses helped immensely with blending and hot spots for me. Loss of par can be overcome by lowering the lights a little and or increasing the intensity. Food for thought.![]()
run for 7 hours/day50% white 50% blue
Are you still running this setting? I just turned mine to 100 blue 20 white last night and came across this. How is growth? I like the way it looks but want to make sure its good for both lps and spa.100 blue, 20 white for me.

How much did par/lux dropped without the lenses?
What lux to par factor did you use? 50?
I want to say it was 60. I calculated a 20% loss in par at the bottom of my tank. I had enough range with the dimmers to make up the difference.
I know this thread is old, but do you have a chart for your par readings?60 blues, 20 whites here. Have to slowly acclimate LPS at this intensity. I am running a 32 inch extreme Wi-Fi on an 85 gal. tank. 150 to 160 par on sandbed at this intensity. I measured this with an Apogee meter.
