Kusuri Formalin

Strong External Parasite Treatment for White Spot & Protozoan Infections in Koi Ponds

Kusuri Formalin is a powerful pond treatment used to support the eradication of White Spot and other external parasitic infections when used in combination with Kusuri Malachite Green.

It works by reducing the fish’s protective mucus layer, allowing Malachite Green to act more effectively against parasites. It is widely used as part of a combined treatment program for common external pond infections.

This is a strong chemical treatment and must be used carefully with correct aeration and dosing.
