"I bought this to treat a betta that I thought was a sure-fire goner. Within hours, he became active, began eating, and pooping like normal. API's Fungus Cure and Jungle Labs Fungus Clear didn't clear his fin rot the way Hikari's Betta Revive did, nor did they treat his protozoan infection.
This product is easy to dose for small tanks and is as close to a miracle cure as you can get!"
