I'd try to frag the lower heads and then slowly reacclimate them to your tank's lighting.

My experience with a hammer coral is that it seems to thrive in low to medium flow. I've placed mine on the sand in a front corner of the tank, and it's doing great there. I have pretty high flow up top with two powerheads and another pump on low, but down low it's a lot calmer.

My branching hammers didn't take to the LEDs at first either. Had to move them to a spot with lower PAR reading. Took about 3-4 days for them to come around.

I'm pretty confident my parameters are spot on, my SPS are thriving and showing great growth. The hammer's the only one that's not cooperating, it looks healthy, full polyp extension and all, just no growth to speak of.

I've been running a Hammer with just 2 heads for 6 months now and I'm not seeing any growth. It looks healthy, full polyp extension, and I've got a decent flow going on - low to med back and forth. I've got a Duncan right next to it, same age, and it's gone from 1 head to 6. I'm stumped. The rest of ...

My single head Duncan's a vibrant fluorescent green, but I've got two new heads coming in and they're currently a pale yellow.
