i have a new 55 gal tank that I had a freshwater Oscar in.. the Oscar caught ick and I treated it with freshwater maracide. The oscar eventually died and I have since washed the tank out and have already bought some products to turn it into a saltwater, will it be safe for inverts? I know that coppersafe is bad, but is this maracide bad as well? I have my sump and everything coming Tues.
