It seems that binox is a mix of nitrofurazone and salt and other mystery ingredients.
The problem is that nitro kills both gramme positive and gramme negative bacteria, and salt adds to that so it will also kill your filter. The makers don't say it won't ( a good clue that it will, otherwise you KNOW they would trumpet about that)
It frustrates no end that manufacturers of fish meds are not obliged to list all the ingredients in their stuff.
