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.
