My tank just began its 4th week of cycling at 70 F/21 C. I'm also treating my goldfish for flukes, with fenbendazole and 0.1% salt.
Would it be prudent to keep replacing the salt after the treatment, to help protect the fish from the eventual nitrites? I read that salt keeps nitrites from entering their bloodstreams. I'll still be doing frequent large water changes, of course. I just wondered if keeping the tank salted would give my fish an extra protective measure when the nitrites appear.
