I picked up a system that I know had ich. It’s been fallow for at least 6 weeks to my knowledge. As I’ve had it for that long, I’d imagine it’s actually longer since his last fish actually died but I didn’t asked him when that was. When I took the tank I trashed the sand, and kept the rock alive. It is now set back up, would you wait for the 76 day mark? Or do you think I’m probably good?
