over the last 12 hours I watched my mushroom melt away in front of my eyes. Why? candy cane did the same 3 days ago. Whyyy? Brittle star died 4 days ago. I did do a terrible job with my salinity last waterchange i think that got my star but i got it back ok over the last three days.Help.

Have you done a water param test recently? Also, how bad was the salinity on the water change 3 days ago?
How long have you had the corals and star and how big were they? How big is your system? What all is in there for livestock? I know that some mushrooms will melt for unknown reasons. I think it's usually the red colored ones. If you just mentioned those that might be it, but may be less likely if you had other livestock die. If you have a smaller tank or a lot of dieoff in a tank it may pollute the water enough to where it affects the other livestock. You might want to get a decent sized water change ready with matched temp and salinity if that's it. |

nitrite-0
nitrate 20-40 p.h. 8.4 ammonia-0 salinity now 1.023 was 1.020 after last waterchange. I did a water change ,15gallon, then the next day bought a lot of gsp and rocks with a bunch of button polyps. buttons opened right up gsp started the next day. three other mushrooms i have also closed. 1 peppermint shrimp died. had the candycane about a month before death, brittle star about two months before death. Now i have just 3 damsels and 3 or 4 peppermint shrimp. i hope. also the usual snails and crabs. I also have a couple zoo frags that are still happy. |

That's a sizable change in salinity, especially if it happened fast. Also, how much the temperature changed could have played a large role.
Match temp and salinity with changes every time as closely as possible. Use RODI water as a much better step than any water conditioner. |

Can you offer more info like tank size, sump size, what kind of filtration?
How did you prepare the water for your water change? Did you use ro/di water? Did you let it set for a day before adding to the tank? How quickly did you add the water to your tank? Could you test the water you mixed the salt with to get an idea of nitrate params there? How long has the tank been up and running? Did things crash only after the water change, or after the addition of the corals and rock? Did you treat the coral and rock before putting in your tank? Have you noticed any nasty creatures which may have hitchhiked in on your rock/corals, either big or small? The thing there is that one friend ended up with a flat worm (small creature) problem where when they die, they make the water toxic. Another friend told me about buying new rock and ending up with dead things. He found the got a hitchhiker lobster of some sort (larger creature) that was killing things at night when the lights were off. So narrowing things down to the water change or the addition of rock matters. Hopefully the answers to those questions will help narrow things down as to what happened and why. I'm really, really sorry for your losses. Not much to do now but figure out why it happened so it doesn't happen again, right? Chin up  BTW, don't toss any corals you assume are dead unless you are sure. Some can actually come back. I had xenia come back from nothing but a couple specs left on a rock before. NCC |
