Binox = Nitrofurazone and salt. Nitrofurazone itself is still available.
I bought Bifuran to replace Binox, but haven't used it yet, so not sure how well it works.
I've used Kanaplex for bacterial infections before, and it did the trick, but is kind of spendy compared to the other mentioned meds, as the others are easy to find larger quantities of (can buy by the KG)
