When fish show symptoms of a bacterial infection, or as a quarantine solution before adding new fish.
Acriflavin can be used in conjunction with Ulcer Swab and Propolis Wound Seal for the treatment of ulcers and other open wounds.
Suitable for koi only.
Test your water quality using NT Labs Pondlab Test Kits.
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 on our website; 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.
Always treat when you have time to observe fish and take appropriate action in the unlikely event of a bad reaction.
