Splitting hammer in trouble!

Sandyego reeyfur · Jul 26, 2019

Hi all this hammer as been in my tabk for about a week now it hasnt fully opened since i got him whereas the frogspawn and other hammer i got opened up almost immediately. The hammer is definetly in the process of splitting but his polyps have recently receded a lot and some of the polyps have fallen out. One of the new mouths looks like it has another mouth comming out of the middle of it. I did a water change yesterday and noticed it looking this unhealthy this morning. Could it have something to do with that. All water parameters are good but i wont have a way of testing alkilinity and calcium levels until this monday when my test kit arrives in the mail. Its not under any more flow then the other healthy corals so i dont rrally know what is going on. I would assume if it was a water quality issue all the corals would show sigbs of distress not just one. Could it be going through a rough split. Has sometging like this ever happened to someone with a splitting hammer/euphillia?

Well could you be more specific about all the available water parameters that you can provide for the time benign. How did you acclimate it, did you dip it? What sort of lighting are you using? Where is it in the tank? What kind of flow and lighting is it recieving? I’ve never really had a problem when my euphyllia split and I have all types of them, frogspawn, hammers, torches, indo and Aussie. What other corals do you have? What corals do you have sitting right next to the hammer? Also how large is you tank? And how old is it?

It’s really hard to tell you anything without any hard numbers alk specifically. Sometimes when LPS corals such as hammers go under it is because of magnesium deficiency in the water column. I highly suggest that you take your water to your LFS And have them test alk ca mg no3 po4 no2 no4. And if you do decide to dose, dose slowly as corals do not take kindly to swinging water parameters.
For the time being you could do more water changes, but I can’t really suggest more without knowing more.

Nitrites and ammonia is zero i think nitrates is 10 ppm i did a water change yesterday it was sitting next to a hammer and frog spawn that are both currently doing really well but i moved it to an area with less flow just now so that less of its polyps will fall off. Salinity is 1.026
