Hammers not coming out??

[Eddie Canupp]

I recently purchased some Mars aqua LEDs and all my corals seem to love them now after slowly acclimating them to the new lights. Except for my branching hammers. They receded and still haven't came back out. It's been 3 weeks. Not even a peek. I did move them. But only to the other side of my tank. Same height and flow as before. Is this normal? Are the goners? Any suggestions? Thanks in advance reefers.

LEDs are powerful and delicate coral such as euphylia etc can take time to acclimate. Either lower the percentage of intensity, or raise the light to see if that helps. GL

Need to move it into a lower par reading. Mine sulked about 3-4 days when I switched to LEDs.

Try reducing your sunlight period to 2 hours, then inch it upward every other day.
