Quick Ich-X utilizes the most widely respected formulation for the treatment of ich, using a less toxic form of malachite green, which makes it less taxing on biological action and safe for scaleless and sensitive fish like Corydoras.
For Aquarium: To treat "ich" disease (ichthyophthiriasis) of freshwater fishes and "marine ich" disease (cryptocaryonaisis) of marine fishes, add one (1) teaspoon (~5 mL) of Ich-X® to 10 gallons (38L) of aquarium water.
