So the past 3 days my hammer coral has been closed up. I tested my water yesterday everything is on acceptable range except my ammonia which is a little high. All my other corals are open doing great. The hammer even has 4 baby heads growing so idk. I’m going to do a water change bigger than I normally do. But just would like some ideas about it. At first it was puffy and open but now it won’t. If anyone has any ideas it would greatly be appreciated
