I just set up 2 new gen 4 pro lights on rms mounts over my 90 gallon 24" deep tank. I am running at 70 percent intensity on ab+ from 12 until 6 with a blue ramp up for 2.5 hours and a blue ramp down for 2.5 hours. i Used a seneye to measure par and the numbers are surprising. I can’t figure out how in the world I am getting 300 par at the sand bed and lower numbers higher up. Is this normal? I was expecting par to go from high to low from top to bottom. The numbers don’t do that. They seem very random. I have attached a par picture and my schedule. I am also curious as to what intensity others use on this size tank.
