PolyGuard is one of Seachem’s strongest medications and ideal for use when you are unsure of the disease or when fish are suffering from multiple infections.
Treats bacterial, fungal & parasitic diseases
Very broad spectrum medication for marine & freshwater fish
Excellent choice when unsure of the disease
PolyGuard treats a wide spectrum of the most prevalent infections suffered by fish, including Fin and Mouth Rot, Ich (white spot), Hemorrhagic Septicemia, and Fungus.
Tip: Many bacterial infections appear along with poor water quality or a preexisting (primary) infection. Test your water for quality and do water changes as necessary to reach optimal conditions before treating with a medication.
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 10 gallons (40 L) 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.
Active Ingredients: Sulfathiazole (36%), Malachite Green (1.9%), Nitrofurantoin (0.14%), Nitrofural (0.14%), Quinacrine Dihydrochloride (0.27%).
Inactive Ingredients: Excipients (61%).
