NT Labs Argusol is an effective treatment for fish lice (Argulus), Anchor Worm (Lernaea) and other crustacean parasites in Koi ponds. NT Labs Argusol is an easy to use suspension of Diflubenzuron which is a powerful crsuteacean medication suitable for koi only.

NT Labs Argusol Dosage:

Dose at a rate of 10ml per 80 gallons (364 litres) - Only use between 10°C and 30°C.

Make sure to shake the bottle well prior to 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 as 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.
