## Features

- 【 ANTISEPTIC AND ANTI-BACTERIAL TREATMENT FOR KOI 】: Use when fish show symptoms of a bacterial infection, or as a quarantine solution before adding new fish.
- 【 TREATS FIN, TAIL & MOUTH ROT AND ULCERS 】: A powerful antiseptic, anti-bacterial treatment for mouthrot, tailrot and finrot. Acriflavin can also be used in conjunction with NT Labs Ulcer Swab and NT Labs Propolis Wound Seal for the treatment of ulcers and other open wounds.
- 【 EASY TO USE 】: To work out the required dosage for your pond, simply calculate the volume of your pond in litres (length x width x depth (in cm)/1000) or alternatively, use our Online Dosage Calculator. Mix the appropriate dosage in a clean bucket of pond water, pour evenly over the surface of the pond and leave for 7 days. Switch off UV filtration until the colour has gone from the water. Aerate the pond well during treatment. If you feel a repeat dose is necessary, check your diagnosis using the Diagnosis Tool; a different medication may be more suitable. Allow 7 days after medicating and perform a partial water change before re- treating or treating with a different medication.
- 【 EFFECTIVE ACTIVE INGREDIENTS 】: Koi Care Acriflavin contains Acriflavine neutral (80 mg/100ml). This ingredient makes it a powerful solution to treat bacterial infections in koi.
