Lights to powerful?

[Devin R.]

Hi,

I have three of the Chinese Black Box LEDs over my 125, 2 are blue and white, the 1 in the center is full spectrum.
I found someone selling a full setup and jumped on the opportunity. So after upgrading from my 16 gallon to a 125 2 months ago, my Blue Hammer started to lose color when it was on the sand bed.
I placed an Acro near the sand bed as an experiment to see how it would do and it's been there the whole 2 months and it's doing fine, so my question is is my lighting to strong for some of the lower light corals if this Acro is doing so well near the sand bed in a shaded area of the tank?
I'll include some photos of the Acro for reference:

Could possibly be. If your corals weren't used to the LEDs beforehand, you may have ticked em off. Do you have the LEDs dimmed at all?

Unfortunately the 2 on the sides aren't dimmable like the 1 in the center. :\

I'd acclimate your corals under the center LED then. Start em at the bottom, and the LED at 20%, then bump it up 10% per week until desired intensity is reached. Hopefully they are on rocks that can be moved.

Yeah they are, thanks for the tips I hope it works! :)
