So i have two 48 inch t5/hybrid fixtures for a total of 8 58W t5's and 4 reefi duo extremes on a 108 inch 24 inch tall tank. In my LPS areas i'm doing great on par, hitting about 120-160 running my LED's at around 50% but my section that i have acro's i'm struggling to get my par where i want it. I have my lights around 10 inches off the water and my acros are like 12-16 inches below the surface but even at 100% im getting barely 200 directly under the LED's. I had heard great things about the duo extremes but surprised i'm not getting more. Is it the depth and no matter what light it's going to be a challenge getting 3/400? or are these LED's just underpowered. I don't think even if i add another led next to it i will get much more directly under due to the positioning/length of the LED itself
