My boyfriend did a water change in my tank a few days ago. I told him not to change too much water at a time but of course he didn't listen and brought my salinity level (and probably pH) down a few points in an hour or less. At first nothing seemed to be affected too badly, the fish clamped their fins for a while but thats it. Now my elegance coral is "sucked in." Did he shock the coral? If he did, will it be ok? I'm so worried....I have such a beautiful Elegance Coral!!
