Awesome Results!


3 of my large goldfish and koi came down with lesions and open sores. After 2 days they were healed! I now use Melafix as a preventative in all my tanks.

Melafix is a great product


This is a miracle product. It does not harm fish; it actually heals them...without harming the other fish in the tank. I use it all the time and have not had any negative effects.



great product, this is the first product that did what it says



Works well and is effective. Just follow the directions

Don't expect miracles...


Melafix works well for most bacterial and fungal infections. It is highly dependent on how early you detect the problem. If used correctly and early enough, it does as advertised.
