  • Strong Anti-Bacterial Treatment
  • Fast Acting
Chloramine T reduces bacteria and parasites in pond water. During cold weather (autumn and springtime) use NT Labs Koi Care Chloramine T to keep parasitic protozoa numbers low in ponds until fish are stronger, more active and can resist them better. At low temperatures, when fish are slow, their immune system is sluggish. Parasites can compromise the fish before their defences have become fully active after the water has warmed up.


50g Treats 22730 litres (5000) gallons
Use a double dose to treat parasites as well as bacteria.
  • Excellent Bath Treatment for all Infections
  • Cleans Pond Water
  • Reduces Chemical Oxygen Demand
NT Labs Koi Care Permanganate is an excellent bath treatment for ulcers, parasites and all infections @ 10ppm dose (10 ml/40 litres - 30 mins). Can also be used for general cleaning of pond water and reducing chemical oxygen demand @ 1ppm dose rate (10 ml to 400 litres). As a treatment to the whole pond, dose at 2ppm (10 ml to 200 litres). The dosage calculator will only calculate a full pond water dose 2ppm level and should not be used for calculating baths 10ppm . 250 ml treats 5,000 litres (1100 gallons) at the 2 ppm pond cleaning treatment dose.

When Permanganate comes into contact with organic material, it breaks down and becomes ineffective as a treatment. To remain effective, the water must remain pink for 10 - 12 hours. If the water becomes brown, the Permanganate is no longer working. Add more, bit by bit, until the water remains pink. This is the reason that permanganate is best used as a bath with clean water which will remain active for the full duration of the treatment.

If you need to neutralise very rapidly because you have overdosed - add Kusuri Hydrogen Peroxide
