Good bang for the buck.


Claims to cause rapid growth of new fins and tissue in as little as 4 days of treatment. In less than four hours it was already making tail rot and mouth fungus look better. Proper aquarium maintenance and prevention will save time in the long run, but Melafix is great when rehabilitating a neglected tank or damage caused from an aggressive fish.

Miracle in a Bottle


The bottle says to use this for 7 days, do a 25% water change, and use as needed for as long as needed after initial treatment. I've only been using it for 4 days, and his fin rot is almost completely cured. This stuff treats everything from tail rot to popeye to cloudy eye and back again! Amamzing!
