Hey guys got a question here about an old 10 gallon tank I once used as quarantine tank for my 57g. I stopped using it as a qt tank quite awhile ago and have since used it as a freshwater tank. Well I have been considering downgrading because I have been out of work and wanted to keep one or two of my fish, with some coral and I wanted to know if it would be safe to set it back up as a salt tank even though it once had copper in it. Or would I be better to just get a new 10g?
