So this is my old quarantine tank. Been sitting like this for about 5 months. The last thing I did was try to treat ich in this tank. Small doses for about 3 days and the fish died and I basically shut this tank down.
I've read different was to remove copper but I guess you can test the tiny amounts leaching until it builds up over a long time. So what's the best way to be sure these rocks are safe? I don't need these rocks necessarily so there is no time limit. I just don't want to waste good rocks if I don't have to. There's always room for another tank somewhere at some point.
