Hello all. I have a Waterbox 60.2 and am currently using a Gen 6 Radion Xr15 and Coral Life 24" Coral Cover Hybrid LED Light Fixture. I do not have access to rent a PAR meter and do not have the funds to purchase one. I am looking for advise as to what to set the intensity at for the fixtures. Currently I am running the Radion at 75% and the Hybrid at 50%, is this to much light? My tank consists of mostly sps, but I do have a few zoas and lps. I currently have the fixture 7" off the water and the sps corals are all towards the top of the rock, with the closest being about 10" from the water surface.
