Okay so at further examination their is something coming off my corals. It looks kind of like a long clear string. It is on a good chunk of my corals. Also, my hammer, frogspawn and radioactive candy cane had them coming off them about a week ago and almost over night have turned into nothing but the skeleton left of them. I did a 50% water change today. I am planning on checking the parameters again this evening. Also, 3 snails have died during this week as well. My levels have always been consistent and regularly do a water change at longest 2 weeks, but usually a 20% change. Any ideas of what might have caused this? All my fish and shrimp seem to be doing well and crabs also are fine. Thanks for any advice in advance.
