Seachem PolyGuard

Overview

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%)

Fin Rot

7 days or until infection clears

Special Considerations

Fin Rot is often found as a secondary infection (that’s an infection that started because the fish was already sick). Make sure to check for additional infections.

Hemorrhagic Septicemia

1 week

Special Considerations

This infection is strongly linked to crowding and poor water conditions. Make sure your fish have clean water and plenty of space.

Ich (white spot)

14 days

Special Considerations

It is very important with this parasite to continue dosing for the full treatment period. A break in the medication allows the parasite to multiply and reinfect the fish.

Mouth Rot

1 week

Special Considerations

Columnaris is very contagious. If possible, remove the infected fish to treat separately in a hospital tank.

Fungus

1 week or until fungus clears

Special Considerations

Fungus is relatively easy to treat and almost never fatal on its own. However, it tends to appear as a secondary infection, meaning there is a more serious disease causing the fish to be susceptible to a fungus.

Dosing Instruction

Dosing in water

Remove all invertebrates - these are extremely sensitive to medication. Turn off UV filters, ozone filters, and remove chemical filtration like MatrixCarbon and Purigen. Use 1 measure (included) per every 8 L (2 US gallons). Repeat this dose every 7 days to a maximum of 3 weeks. This will treat external bacterial infections.

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.
