NT Labs Koi Care Potassium Permanganate Powder – 100g and 250g

NT Labs Koi Care Potassium Permanganate Powder

NT Labs Koi Care Potassium Permanganate is a powdered treatment for koi, available in 100g and 250g packs. The manufacturer lists its use against Costia, Trichodina and Chilodonella, with separate dip-treatment guidance for fish lice, leeches and ulcer cleaning. This is a treatment to choose after checking the problem and the suitability of the pond, rather than an everyday water additive.

These are powder packs measured by weight. They must not be confused with liquid permanganate products, and liquid-product doses must not be transferred to the powder. Use the directions supplied with this exact NT Labs product to establish the correct quantity and method. Your pond or treatment-bath volume needs to be known before you begin.

Pack sizes and product details

Choose a pack using the treatment directions and the actual water volume, not simply the pond’s external dimensions or the number of fish. Displacement, shelves and the working water level affect the volume being treated. Keep a reliable volume record with your pond maintenance notes so that treatment calculations can be checked rather than guessed.

Check the pond before choosing a treatment

Rubbing, flicking and gasping are signs to investigate, not proof of one particular parasite. Start by checking water conditions and observing which fish are affected. A NT Labs Pond Lab Multi-Test Kit is a useful companion for routine water-quality checks. Where the cause remains unclear, obtain a proper fish-health assessment before choosing medication; treating the wrong problem can delay the action the fish actually need.

Write down recent additions to the pond, including salt and other treatments. Check every resident species, not just the koi you are trying to help. A product suitable for koi may be unsuitable for another fish sharing the same water. Temperature and weather are also part of the suitability check, so do not decide from the product name alone.

Important manufacturer restrictions

• NT Labs specifies this treatment for koi only.
• Do not use with orfe, rudd, tench, sturgeon or sterlet.
• Do not use above 22°C, or during hot, humid or thundery weather.
• Do not combine it with salt or mix it with other medications.
• A fish receiving a dip must remain attended; the manufacturer’s maximum dip time is 30 minutes.

Check the pack label each time, even if you have used a similarly named product previously. Product format and instructions matter more than a remembered dose. If the pond contains an excluded species or another treatment is still present, do not proceed on the assumption that reducing the dose will make the combination suitable.

Whole-pond treatment and separate dips

NT Labs gives different preparation instructions for a whole pond and a separate dip. For the pond method, it specifies dissolving the appropriate dose in a clean bucket of hot water and aerating it for 20 minutes before distributing it across the pond. For the dip method, it specifies a separate clean-water preparation, also aerated for 20 minutes. These method summaries do not replace the dose on the supplied label.

Provide strong aeration during treatment. For whole-pond use, the manufacturer advises switching off the UV until the pink colour has disappeared. A treatment plan should include how you will observe the fish and manage the equipment throughout, rather than finishing at the moment the product enters the water. Do not leave a dip running unattended or extend its duration beyond the stated maximum.

What to have ready

Have the correct measuring equipment, a clean dedicated container and the required aeration ready before opening the pack. Keep a clock or timer available for a supervised dip. Read the handling and protective-equipment information on the container, keep the product secure, and avoid exposing children, pets or other pond supplies to the powder or prepared treatment.

Use an air supply suited to the pond’s volume, diffuser arrangement and working depth. If you are reviewing the aeration system, the Oase AquaOxy 1000 is one of our pond air-pump options; choose equipment by the needs of your installation rather than assuming one model is sufficient for every pond.

After treatment

Continue to observe the fish and check water conditions. NT Labs instructs users to wait seven days and carry out a partial water change before moving to a different medication. A repeat dose should follow a careful review of the diagnosis, not an automatic response to a remaining symptom. If fish deteriorate or the cause is uncertain, seek fish-health advice promptly.

The manufacturer also gives follow-up guidance involving its Hydrogen Peroxide product after permanganate treatment. Follow the directions for both exact products and the correct stage of treatment; this is not permission to mix medications or add an unmeasured neutraliser. Keep a record of what was used, when it was used and how the fish responded.

Frequently Asked Questions

Is this the same as NT Labs liquid Permanganate?

No. This listing is for 100g and 250g powder packs. A liquid bottle and a powder pack have different measurement and dosing requirements, even when their names are similar.

Can I use it in a mixed-species garden pond?

NT Labs specifies koi only and lists several fish that must not be exposed. Check all the fish in the pond and choose a treatment appropriate to the entire population.

Are other brands interchangeable?

We also list Kusuri Potassium Permanganate. This is a separate alternative, not a product to combine with the NT Labs treatment. Read each product’s own instructions rather than transferring a dose between brands.
