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).
