• Flukes (Gill & Body) – Trematodes affecting skin and gills
• Other external infections – Fungal, bacterial, and viral lesions

💊 Dosage & Usage

• Standard dosing: 5 mL (1 capful) per 40 L (10 US gallons) daily
• Dip treatment: 3 mL per 4 L (1 US gallon) for 1 hour in a separate container
• Quarantine use: Gentle enough for prophylactic treatment (recommended 2 weeks)
• Sensitive fish: Eels, loaches, rays, and sharks may require partial dosing initially

⚠️ Special Considerations

• Remove invertebrates and chemical filtration before dosing.

  • Ich: 14 days (freshwater), up to 28 days (saltwater)
  • Velvet: 14–21 days (lights off recommended)
  • Fin Rot: 7 days or until cleared
• Do not interrupt treatment – stopping early allows parasites to reinfect.
