Description:
Fungal infections are a common issue in freshwater aquariums and often appear as pale grey or white growths on the skin, fins, or mouth of affected fish. In the early stages, these infections may look like fine thread-like patches, but can quickly develop into small, cotton-like tufts if left untreated.
If not addressed promptly, fungal infections can spread rapidly and lead to serious health issues or losses within the aquarium. This treatment is designed to help manage fungal outbreaks and support fish recovery when used as directed in a well-maintained freshwater system.
Suitable for a wide range of freshwater aquarium setups ONLY. This treatment is best used in well-aerated tanks during treatment.

If you're here, you're already doing the right thing by taking action. While medications play an important role in treating illness, most common fish diseases are closely linked to water quality and tank management. Maintaining a regular water change schedule, avoiding overstocking, ensuring your filtration is appropriate for your tank size and fish load, and keeping fish in a tank suited to their needs will go a long way toward preventing outbreaks in the first place.
If you're introducing new fish, setting up a hospital or quarantine tank is one of the best habits you can build. Running new fish through a 2 to 6 week quarantine period before adding them to your main tank gives you the chance to observe them closely and treat any illness in isolation, protecting the fish you already have. There's no rush, illness can appear at any point during quarantine, so patience here pays off.
