Been doing freshwater for years but added a saltwater tank about a year ago. Added a fish and didn’t have time to quarantine it and now I got icy. I put the 2 fish infected in a quarantine tank and cranked up the temp to 85 and added medication like I have done with my freshwater when they got it. My question is usually the medication and aquarium salt go hand in hand treating it. Should I add aquarium salt to saltwater to help. I know it sounds dumb but I’m confused. Thanks
