Hello Reefers, for lights, I am running 2 Radion Gen 2 pro's with 4 T5 bulbs over a 24" deep 90gal. This last week I rented a PAR meter from BRS and I was a bit surprised by the results, which i I will post below. I am hoping to have SPS on all of the top plateau's and figured it would not be difficult to get a ~350 PAR across each tops which are about 7" deep. The higer readings at the top are about 2". In order to get to the numbers in the graph I have my lights at 11" above the water, cranked the radions up to 100% and using the AB+ spectrum, turned the WC from 24% up to 40%. I feel like I am really having to push hard to even break 300 PAR. Are my rocks just too deep? I don usually see anyone running their radions much over 50%. Would it make a big difference to go to Gen3?
