I recently purchased the Photon V2 Pro and went with the mixed reef preset. I have 75 gallon with little coral at the moment but had planned a mix. I used the mounting brackets, and the light is 12" from the surface. With a par meter I'm getting 120 on the bottom with around 220 toward the top where rocks are currently located, maybe about 5 inch below surface. Is this about right? the BRS showed PAR higher but I think they had every channel at 100%. Just want to make sure I'm setting up for success.
