NT Labs Koi Care Formaldehyde is an excellent anti-parasite treatment, particularly when mixed with Malachite.
Formaldehyde is effective against protozoan parasites and flukes. It is especially useful in treating flukes because of it's ability to penetrate mucus and reach the parasites that would otherwise be protected from other bath treatments. This treatment contains a high level of 30% for the best results.
When parasite infections such as Ichthyopthirius white spot, Trichodina, Costia, Chilodonella, and Epistylis are suspected the best treatment is a mixture of Malachite Green and Formaldehyde. NT Labs have a ready mixed FMG treatment. However some external parasites such as the flukes Gyrodactylus and Dactylogyrus are best controlled using Formaldehyde alone.
Add 10 ml of Malachite Green, to every 352 gallons (1600 litres) of pond water and 10 ml Formaldehyde to every 150 gallons (681 litres).
This is a strong one shot treatment, and is thus not suitable for use with those systems that contain sensitive species such as orfe, sterlet, rudd or tench. Caution: Formaldehyde is a hazardous chemical and should be handled with great care, please read the warnings on the label carefully.
Instructions for use:
When these parasites are suspected apply Formaldehyde at 10ml per 150 gallons (681 litres) of pond water.
250 ml treats 17,048 litres (3750 gallons). The 2.5 litre bottle will give up to seven treatments of 25,000 litres at a time. So the 2.5 litres gives you 10 times the treatment but at less than six times the price.
