Bacterial Treatments.
When an infection takes hold — ulcers, fin and mouth rot, stubborn secondary infections — you need a real antibiotic, dosed correctly. Pro-grade treatment you can run through medicated food or the pond itself.
Treat Responsibly
- Follow the label dosage and finish the full 14-day course.
- Food treatment is the recommended method.
- For pond dosing, bypass UV and bio filters and do daily 50% water changes.
- Don't under-dose or stop early — it breeds resistance.
- Review the SDS and warnings before you begin.
