earlier in the summer we had something go wrong in the tank, and it started to wipe out all the corals. I lost all the hairy mushrooms first, which was so strange since they had been so easy to grow and dominated the tank. Then I lost all the ricarodia,zoos, and all my blue mushrooms.I loved the blues, so that was the worst part

. I lost all the
green striped mushrooms,
candy cane corals, some frogspawn.
It started along the left side and just wiped things out as it seemed to cross the tank in a matter of days. It looked like something with a bit of a web was in the tank. We did major water changes for several days and it finally stopped. It was pretty scary as we were watching things rapidly disappear. It did not harm any fish, but I did lose my two shrimp. It also did not affect any of the leather corals or the anemones. The few mushrooms that it did not reach also remained in tact. Never really found out exactly what it was, but we were glad to be able to stop it and not have it harm the fish.
The tank looks much different without all the color now, but we have waited to add anything since we are going to be doing a tank upgrade within the next month or so. I have just been fragging the leathers. Hopefully the fish will do ok with the tank transfer. If all goes well, we will add some new corals. It makes me a little hesitant now to get much for corals, since overnight basically they can diasspear if something goes wrong. We had been so lucky for our 2 years in the hobby,
I will post a before and after the problem. I will also post again when we get the new tank.
