Hammer coral help...

I have a hammer coral that I received from a fellow reefer.

Hammer was under PC lighting when I first got it. Was 4 heads then split to 8 in our 26 Gal. It was in our 26gal for about 4 months and very healthy. We then moved it to our 120 with AI SOL LED's when we upgraded. For 2 months it was just fine and some heads split again, now have 13 heads. Ever since it split in the 120 it has gone down hill. Most heads have fully receeded and the ones that are open are not even close to fully open.

Water parameters are very stable and have been. We feed sun polyps 3 times per week and all corals with "Reef Chili" once a week. The hammers are placed on the very bottom of the tank and are not under direct light. They are also away from any other corals that could be bugging them.

Just a little dissappointed with their health lately. Our 120 was set up with all intentions of being an SPS dominant tank but I still would like to keep LPS as well.

Any insight is appreciated. - Thank you.

I can post a pic later if needed.
 
Could be the flow on them if it was a sps dominate tank the flow might be to much for them. There could be alot of different things a picture would help and knowing the parameters of the water would be better. JMO I think it could be flow more then anything they like some but not alot. mine I have on rockwork about mid level with light flow across it.
 
I'd like to see a pic as well. Mine seem to enjoy being in the light, I don't know how powerful your LED's are but adjusting how much light it's getting may help.
 
Here's a picture of the suspect.

Also the skin or whatever on the top head just showed up today.

I have a lot of flow in the tank but not much on the hammers and no more then they've been subjected to.
 
Parameters this week are:

Calcium 430
Alk 10.5
Mg 1300

Calcium never drops below 400, Alk never drops below 9.5 and Mg swings the most but is typically above 1250 ppm and if lower it's not too much lower.
 
Still hasn't started to come around.

Think it's a lost cause at this point?

I did move it to a bit darker spot in the tank with low flow, but I have yet to see any improvement.
 
It died.. We attribute it to LED intensity issues, not flow or water chemistry. Our corals had been showing signs of too much light and we have come to realize it was a lack of light causing the bleaching and melting. Therefore, we bumped up the intensities and our corals that are still alive are showing polyp extension and some overall happiness. LEDs are tricky
