Instructions for Use

Dosage Guidelines

✔ 1 capsule (100mg) per 10 gallons of water.
✔ Repeat every 24 hours for 5-10 days, or as advised by an aquatic veterinarian.

Treatment Process

⚠ Remove Activated Carbon Filters before treatment begins.
⚠ Perform 20-50% water changes between doses.
⚠ Complete the full treatment course, even if symptoms improve early.

For best results, quarantine infected fish to stop the spread of bacteria in the main aquarium.

Important Considerations

⚠ Confirm Bacterial Infection - Fish Doxy only treats bacterial infections, not fungal or parasitic conditions.
⚠ Monitor Water Quality - Maintain proper water parameters to prevent stress on fish.
⚠ Sensitive to Light - Doxycycline is light-sensitive, so dim the aquarium lights during treatment.
⚠ Consult an Aquatic Veterinarian - If symptoms persist, seek professional guidance.
