Instructions for Use

Dosage Guidelines

✔ 1 capsule (100mg) per 10 gallons of water.
✔ Administer once every 24 hours for 5-10 days, depending on infection severity.

Treatment Process

⚠ Remove Activated Carbon Filters before starting treatment to prevent medication absorption.
⚠ Perform a 20-50% water change between doses to maintain clean water conditions.
⚠ Complete the full treatment course, even if symptoms improve before finishing.

For best results, treat infected fish in a quarantine tank to prevent contamination in the main aquarium.

Important Considerations

⚠ Correct Diagnosis is Essential – Fish Doxy treats bacterial infections only, not fungal or parasitic diseases.
⚠ Monitor Water Quality – Maintain stable water parameters during treatment.
⚠ Light Sensitivity – Doxycycline is sensitive to light, so dim aquarium lighting during dosing.
⚠ Consult an Aquatic Veterinarian – If symptoms persist, seek professional guidance.
