PolyGuard is the single most effective medication to keep freshwater fish free of disease! It is an effective treatment and safeguard against all prevalent bacterial, fungal, and parasitic diseases of exotic fish. Contains malachite green, sulfa, quinacrine, and nitrofurazone medications

• Ingredients: Sulfathiazole; Malachite Green; Nitrofurantoin; Nitrofural; Quinacrine Dihydrochloride; Excipients
• Use Instructions: Before Treating: Remove all invertebrates - these are extremely sensitive to medication. Turn off UV filters, ozone filters, and remove chemical filtration like MatrixCarbon™ and Purigen®. Ensure that your tank is fully cycled and stable; poor water quality is the root cause of most fish diseases, and adding medication will do no good if the water chemistry is still bad.Dosing: Use 1 measure (included) per every 40 L (10 US gallons) of water. Repeat this dose every 72 hours for a maximum of 2 weeks. Repeat every 3 days for up to 2 weeks or until symptoms disappear. Use whenever introducing new fish.After Treating: When the treatment period is over, PolyGuard™ can easily be removed using activated filter carbon like MatrixCarbon™. It does not linger in the substrate or filter media of the tank.
