Ok so I get home from work I had put them in the pail, everyone was alive and happy swimming in the pail when I got home. So I take some water into golds to have it tested ammona is fine no traces, Nitrite is fine nothing, everything is good. So I tell them the story of how it started off with ICH and then how everyone was breathing every so heavely yesterday morning and the fish that looked totally fine died.... SO I tell him how I had this new little ananome and it wouldn't open up and he said AAHHHHH that is the problem its leached its toxin into the tank cause it was stressed! so I come home do a 50% waterchange on the tank, put TONS of carbon in the filter and put all the fish back into the tank (no ananome) I had taken it out that morning with the fish, so just the fish go back in. OK well everyone except the blue tang cause of the freshwater dip I did looks good. SO I clean up everything thinking ok well that is good everything is going ok now. OK here is where it gets bad again, not even 2hrs later I look into the tank and OMG everyone is at the surfice breathing rappily again! I'm like What the Hell is going on here! so again I know I shouldn't have done this but went into panick mode, and made a new fresh saltwater pail and netted them all put htem in the pail and OH I expected them to all be dead this morning NOPE there all swimming around! even the blue tang... SO what the hell is going on. I have 30 pounds of live rock and nothing on it seems to be affected I don't have corals but like all the living little things on it are alive, like little tiny shrimps, feather dusters etc. even my porclin crab is fine in the tank. Its a 33gal been up and running for 4years no problem, I have a aqua clear 50 filter on it with just carbon, I have 2 aquaclear powerheads for water circulation and movement. I have the heat at 80 degrees. I have a UV starilizer on it, what the hell is going on oh yeah and about 30 pounds of LR 20 of which is new I got from a really nice Canreefer here. I am so totally lost on this and I don't know what the hell to do, if I put them back into the tank are they going to die I know they won't make it if I keep moving them that is stressful enough on them. I am trying everything I can to not loose anymore.
