Seachem PolyGuard is the single most effective medication to keep freshwater fish free of disease! It is an effective treatment and safeguards against all prevalent bacterial, fungal, and parasitic diseases of exotic fish. For use in freshwater or marine aquaria. Be aware that many diseases and infections share similar physical and behavioral symptoms, e.g. clamped fins, lesions, and loss of appetite.
When our pets are sick, we immediately want to reach for the most powerful medication on the shelf. However, sometimes the right choice to prevent stress is to opt for a gentler medication at first, especially with less severe infections. PolyGuard is among Seachems strongest medications and is best used when you are unsure what disease you are treating or when the fish is suffering from multiple infections.
Active ingredients: sulfathiazole (36%), malachite green (1.9%), nitrofurantoin (0.14%), nitrofural (0.14%), quinacrine dihydrochloride (0.27%). Inactive ingredients: excipients (61%)
Before TreatingRemove all invertebrates - these are extremely sensitive to medication. Turn off UV filters, and 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 TreatingWhen 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.
