Hey everyone,
I re-shot the video after tweeking some of the settings on the excel file. also, stay tuned as we combine this method with a par meter over the weekend!!

Interesting. I didn't realize channels 3&4 were higher watt LEDs.
I've been running AB+ but I guess not exactly due to diode watt differences.
Thanks

Following. I've had issues with setting these lights up. I've cooked several corals trying to dial this thing in.

Get a hold of a PAR meter. My experience is getting these higher off the surface and keeping the white channel lower will help. At least 12" and lots run up as high as 18-20" above the surface.

I have a PAR meter and it’s 16 above surface. I was at 275-300 but I think whites were to intense. Lowered those and increased blue spectrum. Got them at about 200 par now. Will increase from there as needed.

I just went from 6" to 12" (couldn't get higher before due to canopy) and I'm running the whites, reds, and greens at 10% with the others at 40%. I use two Orphek bars though also angled front and back. I'm getting 400+ on higher rocks.

unfortunately the PAR meter had to be put on hold last week end. A few other things popped up. but it sounds like we will get it done this weekend

Did you ever get the PAR figures?

dputt88 · Mar 30, 2019

I did. I'm still working on getting around to the video but I was a bit high. Some of the higher areas of the rock work were getting as high as 310. the sand bed was 225. I had to lower the whites down a little bit and i raised my fixture up an additional 6 inches. next weekend we will try to retest the PAR readings
