It is a frag tank 12" deep corals sit about 6" below the water. I just lower the light about 3" and I get par between 300 and 400 now. I think with reeflink I hed more par then mobius, Ren light at 60% and par was in that range with same template ab+. @dmythank you for your input. I checked what u said and if I raise all the channels to 100% the graph points will go to 100%.
