I've had these leds for a few month now.I bleach 2 colonies of Birds nest among many other coral.Tried dimming in various amounts,also pulled optics off.Lights 16" off the tank.3 fixtures over 5 foot 120 gallon.I don't want to go back to T5.

I have pics before leds I'll add current pics later.

What type of lights are they ? And how deep is your tank ?

What fixtures do you have and what percentages have you been running them? when I first switched over to LED's I had to run my AI Sol's at 30% and slowly build up from there, it took me over 3 months to build up to the 70% that I topped out at. The corals lost a bit of color during the acclimation process but I didn't have anything bleach.

Man I feel for you. I went through a similar situation. A PAR meter will help but not solve all you problems. My SPS loved the LED's at first then a long slow decline from there. I tried to match a friends PAR numbers from his halide set-up and the SPS still bleached. I had to set them at half the amount he had and they did okay. I tweaked and fiddled for about 10 months and went back to a halide/T5/led set-up. Replacing all that coral is not as cheap as a bulb change for sure.
