I am using this from long time. Many says fish dies. Its true. But you need to be very careful while using this. Donot forget to turn on the filter and oxygen when ever you put the medicine. Weekly once or twice you can use this. If water gets cloudy next day you can remove the half or quater and refill with the fresh water. But if you have tetras / neon tetra / guppies use very less amout of medicine. For shrimps / bettas no problem..

Nice
