Product Description


NT Labs Koi Care - F-M-G Mixture



White spot, TrichodinaCostia and Chilodonella.


When to use?
When fish show symptoms of a parasitic or fungal infection, including white spots along the fins and body, flicking and rubbing, gasping at the surface, an opaque film over the body or fluffy, white growths.


How to use?

  • Test your water quality using NT Labs 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.
  • 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 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.



10 m per 80 gallons (364 litres). If necessary, perform a partial water change and repeat the treatment 7 days after the previous dosage. The treatment can be safely repeated up to 4 doses.
