New tank setup i got 75 gallon tank an bought 2 gen 5 xr30 pros for it how high do I need to mount them an what settings/ percent do I need to run them these are my first radions I plan on having a mixed reef

I try and run my light about 11-13 inches off the water, but honestly it will all depend on the tank and adjust on how much light spills out of the tank, and also on PAR readings. if you can get a hold of a PAR meter to test that would be the best option as you will know at what intensity, and height your lights would be best suited.

I mount my xr15 about 8 to 9 inches above the water at about 40% AB+ with T5 hybrid lights.
