NT Labs recommend using the Koi Care Argusol when fish have large external parasites, Argusol is an easy-to-use suspension of diflubenzuron which is a powerful anti- crustacean medication suitable for Koi only.

How to use:

  • Shake the bottle well before use. Mix the appropriate dosage in a bucket of clean pond water, pour evenly over the surface of the pond and leave for 7 days. Switch off UV filtration for 10 days from adding the medication. Aerate the pond well during treatment.
  • If you feel a repeat dose is necessary, check your diagnosis carefully, a different medication may be more suitable. Allow 7 days after medicating and perform a partial water change before re- treating or treating with another medication.
  • Always treat when you have time to observe fish and take appropriate action in the unlikely event of a bad reaction.
  • 500ml treats 18200 litres/4000 gallons
