How long have you had it? Are those zoa’s right beside it, they don’t look like they are doing well either. Need more info on your tank lighting and flow and parameters
 
I hope that’s any better

Going on two weeks, they were doing very well till today, and no no zoas, all hammers. I run kessils a360x and flow I’m not sure if they getting to much?
 
Pictures under white light would help. The one on the right in the front looks like it is melting. Hate to be the bearer of bad news for you, bud.
Melting? What could be the cause anyway to save them
 
If the flesh band is receded and the tentacles are looking limp—- I believe there is a possibility of bacterial infection. The iodine dip is basically a "medicated bath" that would kill pathogens without harming the coral tissue. It’s a preemptive approach.
 
Ammonia - 0
Alkalinity 9.9
Not sure of calcium or magnesium haven’t got it checked
Ph - 7.8

All my corals seem to be doing very well jut not the hammer
You really need to invest in, nitrate, phosphate, calcium and magnesium test kits. Salifert are very affordable. Unlike soft corals, hard corals are very dependent on magnesium and calcium for skeletal growth.
