The Seachem PolyGuard Treatment for Fish is the most effective medication for keeping freshwater fish disease-free. It is an effective treatment that protects exotic fish from all common bacterial, fungal, and parasitic diseases. For use in freshwater or saltwater aquariums.
When our pets become ill, we instinctively reach for the most potent medication on the market. However, when dealing with less severe infections, it is sometimes best to start with a gentler medication to avoid stress. PolyGuard is one of Seachem's most potent medications, and it's best used when you're not sure what disease you're treating or when the fish has multiple infections.
When the treatment period is finished, PolyGuard can be easily removed with activated filter carbon, such as Seachem MatrixCarbon. It does not linger in the tank's substrate or filter media.
