Description Pure Malachite Green powder delivering precise dosing and better value per treatment for freshwater and saltwater ornamental fish. Purchasing pure powder rather than a premixed bottled product allows for precise dosing and significantly better value per treatment. Zinc free, confirmed by the distinctive green color of the powder — zinc would otherwise produce a colorless product. Most commonly mixed with tank water or formalin. Once dissolved potency decreases over time, so preparing a fresh solution for each treatment delivers the best results. Not recommended for use with invertebrates Toxic to live plants Use caution when dosing. May cause gill issues if overdosed. Sensitive species including small tetras, catfish, and scaleless fish require half doses. Turn tank lights off during treatment as light reduces effectiveness. Can stain tank glass, silicone seals, and decor. Use protective gear when handling. Avoid skin contact and inhalation. Pregnant individuals should avoid handling this product. Increasing water temperature during treatment speeds up the parasite life cycle and can reduce the required treatment period.
