Seachem PolyGuard

Seachem PolyGuard is used to treat bacterial, fungal, and parasitic diseases in freshwater fish.

  • Treats bacterial, fungal, and parasitic diseases
  • Very broad spectrum freshwater medication
  • Good choice when unsure of the disease

Seachem 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.

Types of Infections Treated: Parasitic, Funal and Bacterial

Directions
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.

Active ingredients: sulfathiazole (36%), malachite green (1.9%), nitrofurantoin (0.14%), nitrofural (0.14%), quinacrine dihydrochloride (0.27%). Inactive ingredients: excipients (61%)

My puppy loves this chew toy.
Style: Goal Post Chew Toy, Color: Detroit Lions
It’s one of his favorite toys to show off and chew. I constantly find him carrying it around. The only downside is that the Lions emblem wore off really quickly. It’s still a super cool toy though.

Heavy nylon. No squishy or chewable for pups.
Style: Goal Post Chew Toy, Color: PHILADELPHIA EAGLES, Style: Goal Post Chew Toy, Color: PHILADELPHIA EAGLES
Photo is just for size comparison. It’s really hard and not chewable but he’s already put a dent into it, as you can see. Not sticky, smells right out of the packaging !! We loved that! Its size is about a 20 oz Powerdrink but it’s sturdy and heavy. It’s going to last us such a long time . The only thing is the logo might be worn off sometime soon. Go birds! 🦅

Perfect toy for an active dog!
Color: Large size (7.9")
My dog absolutely loves this ball with handles! It’s quickly become one of his favorite toys, and he gets excited every time we bring it out to play. The vibrant colors are a huge plus—they make it super easy to spot in the grass, which saves a lot of time during outdoor play sessions. The handles are great for interactive play too, especially for tugging and tossing. I’m really impressed with how well it’s holding up. Even with constant pulling, tugging, and rough use, it’s remained durable and hasn’t shown any signs of wearing out. Overall, I’m very happy with this purchase—and if my dog could write reviews, it would definitely get his paw stamp of approval! 🐾

Not for strong chewers!
Color: Large size (7.9")
I have an English Springer Spaniel who is 1.5 yrs. She had this torn apart within the first 5 minutes. This is not for strong chewers!
