hi! :thinking:
I'm assuming you have live rock and plants. If you treat your tank with copper, you are sure to seriously hurt and/or kill all of that; a serious loss!
I 've had two breakouts myself, one was ich and I did what you're going to do....it killed EVERYTHING.
EVERYTHING!!
I had to start completely over and my fish did not live either.
DEFINATELY NOT WORTH IT!!!!
The next time I got a worm breakout and pulled my fish out and put them in a 10 gallon tank.
You're supposed to put them in the same water they're in now, with the same sand and a few ornaments from the old tank. Keep in mind you will not be able to put whatever you take out of your big tank and put into your small tank back into your big tank, so choose simple things that will make the fish feel safe but you can replace easily. You can treat the fish in the small tank with copper. The copper will soak into the sand and ornaments, so you shouldn't put them back into your big tank. Copper is harsh and will kill not only live rock and plants, but also inverts.
Keep your big tank going as usual for at least two weeks (this is also the time frame you're supposed to treat fish with copper). The justation period for ich is one week, but then you have the eggs in the sand, so it takes at least two. I left mine for three and everything is fine and alive. Best of all, I didn't have to start over like I did the first time.
* My plastic hydrometer only cost about $2- at PetsMart.
* Yes, remove the carbon if you treat your tank.
I know you need to get right on this, so I'm posting this now, but PLEASE ask me anything if you choose to do this!
BEST OF LUCK!!
