Description
Fritz Maracyn Two is a powerful board-spectrum antibiotic designed to treat bacterial antibiotic infections in both freshwater and saltwater aquariums. This trusted aquarium supply effectively combats negative bacteria, which cause infections such as fin and tail rot, popeye, septicemia, dropsy, and internal bacterial diseases. Unlike external treatments, Fritz Maracyn Two is absorbed through the fish’s skin, ensuring deep, systemic relief. It's a great first-choice treatment when the cause of illness is uncertain and can be safely used alongside other Fritz medications like Maracyn and Coppersafe.
