I didn’t change this post because it’s correct for 14” above the waterline but I lowered the light and PAR was dramatically higher. Will post new results soon.
Rented a PAR meter today. Good news is with the 3D Reefing diffuser and 14”AWL the par readings are very flat from rock to sand and all around. I can achieve a par variance of <20 below 100 (80-100 total range) and <40 below 180 (140-180).
The bad news is I was hoping for some spots in the 200-300 range for some SPS. Perhaps I can find a lighting program that I like the color of with some more par.
I’m currently using the BRS LPS spectrum for a 60 cube and tweaking up and down from there. cranked all the way up it’s still not hitting SPS range. The diffuser cuts about 15% PAR so I can get there without the diffuser but I like the diffuser.
I can put some lower light stuff at 180, but it will be very limited.
I think I’ll need to be happy with an LPS tank unless I change lights.
