Hi everyone, I am adding the final set of T5HO to my 65 gallon reef, right now I have 4 - 39watt T5HO. I made my canopy I don't have a lot of room. I need to raise my lights 1.5" to get all three sets of the Aquatic Life lights to fit in. Will raising my lights greatly reduce my light penetration. I want to start some SPS corals I have one monti cap and it is doing fine. Thanks for looking.
