Instructions for Use

Dosage Guidelines

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

Treatment Process

⚠ Remove Activated Carbon Filters before treatment to prevent absorption of the medication.
⚠ Perform a 20-50% water change between doses to keep the tank clean and safe.
⚠ Complete the full treatment cycle, even if symptoms improve early.

For optimal results, treat affected fish in a quarantine tank to avoid spreading disease.

Important Considerations

⚠ Correct Diagnosis is Essential – Fish Doxy treats bacterial infections, not fungal or parasitic diseases.
⚠ Monitor Water Parameters – Keep ammonia, nitrite, and nitrate levels in check during treatment.
⚠ Light Sensitivity – Doxycycline is sensitive to light, so dim the aquarium lights during dosing.
⚠ Consult a Veterinarian – If symptoms persist, seek professional advice.
