Need some opinions for my lighting rank situation. How should I mount the T5s? The XR30s and Halides will be 12-13” off the water. I was told the T5s should be 7” off the water. I like the angle I have them at as the tank is 3 foot wide. And at this angle there should be a nice spread. I have the high intensity lenses on the XRs. If I put the T5s horizontal to the ground, won’t I lose spread being so close to the outside of the tank?
