Kordon Rid-Fungus™ is an easy to use treatment composed of 100% multiple organic ingredients for all types of external and epidermal single-celled infections. It's broad spectrum of activity and lack of toxicity makes Rid-Fungus effective without requiring a specific diagnosis. It stops infectious and external parasitic invasions from getting started and in turn prevents many secondary infections. In short, Rid-Fungus suppresses and eliminates a wide spectrum of infections.

Rid-Fungus is effective against protozoan parasites on fishes and aquatic invertebrates, whether fresh or brackish water, or marine. These comprise dozens of genera and species of fish-infecting species in fresh and salt water, each kind with distinctive characteristics in their infections. The groups include "white spot disease" and other ciliates (Ichthyophthirius in fresh water, and Cryptocaryon, Brooklynella, Trichodina in marine), and "sporozoan parasites" (for which many infectors of aquarium fish are marine).
