Medications
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. For use in freshwater or marine aquaria.
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 Seachem’s 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%)
PolyGuard™ is appropriate for treating a variety of bacterial, fungal, and parasitic diseases of exotic fish. Below are some of the more common diseases treatable with PolyGuard™. Be aware that many diseases and infections share similar physical and behavioral symptoms, e.g. clamped fins, lesions, loss of appetite.
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.

A: As a general rule of thumb, I would not mix medications. If you feel you must, please watch your fish closely. Water exchanges should be performed after the complete 2 week dosage (4 total doses) before continuing with anther 2 week dosing of PolyGuard™.
A: PolyGuard™ is different from ParaGuard™ in the fact that PolyGuard™ contains antibiotics and ParaGuard™ acts more like a disinfectant/antiseptic and does not contain antibiotics.
