Malachite Green & Formalin
Formalin is Formaldehyde at a concentration of 37% in water and can be used as a parasite treatment on its own or in conjunction with Malachite Green.
This product combines both Malachite Green & Formalin and can be used against protozoan and metazoan (multi-celled) parasites, as well as a good general-purpose anti-parasite treatment for Ichthyophthirius (white spot) and Saprolegnia (fungus) infections.
Dosage & Directions For Use
Wear gloves and goggles when handling malachite green and formalin. Do not inhale the fumes and always handle in a well-ventilated area. Once the correct dosage is measured, pour directly into the main pond.
Special care should be taken when introducing Formalin into your pond water as it has the potential to kill already weak fish as well as harm your filter bacteria. The water should also be oxygenated at all times.
Dosage: Malachite: 0.1mg per litre with 25mg per litre formalin.
Storage: Store below 25°C in a dry place out of direct sunlight.
Caution: Not for human consumption. Keep away from children.
