Product Description


NT Labs Koi Care - Argusol



Fish lice (Argulus), anchor worm (Lernaea) and other crustacean parasites.


When to use?
When fish have large external parasites, Argusol is an easy-to-use suspension of diflubenzuron, a powerful anti- crustacean medication.


How to use?

  • Test your water quality using NT Labs Test Kits.
  • 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 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 another medication.
  • Always treat when you have time to observe fish and take appropriate action in the unlikely event of a bad reaction.
