I am currently running a Red Sea ReefLED 90 on a Red Sea Max E-170 and it seems to be really powerful. I am getting what seems to be burnt tips and bleaching on my acros with the light dialed back to 70% and running for 12 hours a day with a 1 hour ramp up and down period. I am going to turn it down to 50% tonight and rent a par meter to test more exact specs on it tomorrow, but just wanted to see if anyone has used this and what their lighting schedule and setting looked like
