Thanks Marvin! Your clown/nem tank already looks pretty mature to me. The last zoomed out pics you posted were incredible!
I'm not sure on the optics, but the driver I'm using is the Meanwell LPC 35-700. In retrospect, I wish I went with the dimmable driver so that I could ramp up the lighting instead of just on/off. The growth is good in the frag tank, but the coloration isn't that great due to my LED combo. I'm running a 1:1 ration of RB:white diodes, so it's about a 10k spectrum. Great for growth, but SPS doesn't really color up. If I could do it all over again, I would use 18-24 diodes instead of 12 and put the whites & blues on seperate dimmable drivers.
