I'm new here. I bought some fish at a big box store and didn't quarantine. I ended up with ich and lost many fish and fry. I've since added a UV filter and a second top filter. I've also started using aquarium salt & better conditioners. I haven't seen any spots since late August. I've also started using biosponges. I have 8 new fish in my quarantine tank and I'm afraid to move them to my main tank. I've had the 8 new fish about 3 weeks. They seem well. I almost don't want to move them but I need to introduce new fish to reduce inbreeding. Is it safe in my main tank yet? Or am I going to expose the new fish (all different types of guppies only) to the ich i previously fought?
