Weird. I have copper and I'll be running it soon. The only issue is I'm waiting on my test kits for it. I've since then pulled all of my fish out so I can begin copper treatment on everything. I'll leave the tank fowlr for 3 months as well.
I'm having trouble getting some chromis out though and a hippo tang, anthias and coral beauty. Any suggestions?
i know this sucks but take as much rock out as you reasonably can. My coral beauty was a bastard to get out and all i have is a 40 breeder.
Edit: wait what, your leaving your tank FOWLR(fish only with live rock.) you sure you dont mean FALLOW?(Fishless.)
I thought it was in a QT. Are there a lot of other fish in the same tank?
i hope he treats them and gets them well before he sells them.
