My fish had ICH so I moved my riffle shrimp into a bucket with a new filter, which my LFS said would be fine. I have lost 2 of 3 shrimp and my filter stopped working. I am treating my fish with copper (which kills the shrimp) and have been running carbon for a day. My LFS said there was still a bit of copper left in the water. My filter just kicked out (I don't know why) and was wondering whether my shrimp could survive with a tiny bit of copper left. I placed heaps more carbon in an effort to speed up the process... What do I do??? Is my filter producing something that is killing my shrimp? Where do I put them now? What do I do? Please help!
