Acriflavine
Ingredients: acriflavine
Diseases: Brooklynella hostilis, Costia (Ichtyhobodo necatrix), Columnaris, Carp Pox, Fin Rot and other diseases related to bacterial infections
Comments: Acriflavine is found mainly as ingredient in several medications and is very effective in most bacterial infection cases.
This was one of the ingredients in a med for bacterial infections I used. I wouldn't personally used it in planted tanks especially as it kills your beneficial bacteria as well.
