Sure enough the first time I didn't quarantine my fish came down with ich. Or at least I assume so by the spot on my tang's fin, and my puffer looks like he had salt sprinkled on him. My question is can I set up a small quarantine tank to keep these guys in & dose them without it having been set up previously and cycled? I've got a biowheel HOB filter that might have some nitrifying bacteria on it that I can transfer to the quarantine, and have thought about transfering some of the sand bed in the hopes that it also had colonies. Maybe some of the live rock? Any suggestions would be greatly appreciated!!
