Quick Cure/Malachite Green/Formalin Warnings
This makes me so mad that Quick Cure does not put warnings and precautions on their product's packaging, because these mistakes are made all the time and are incredibly dangerous to fish. Quick Cure is a strong medication for ich and other parasite infections with two main active ingredients: Malachite Green and Formalin.
Malachite Green is sensitive to light, and is usually sold in dark colored solid bottles at the store. When it comes in contact with light, it will become ineffective and it will not help your fish at all. Store in a dark place. When medicating a tank, cover the whole thing with thick dark towels or black trash bags, and keep the light in the room to a minimum.
Formalin and salt do not mix, and this combination will make your fish even sicker than they were before. This is often true for other anti-parasite meds, so always research before mixing anything in the water. As formalin degrades and ages (goes out of date) it forms a white precopate. This is Paraformaldehyde and will kill fish! If you notice a white film or any white color to the medication at all, toss it out. Never use old medications, even if they don't have an expiration date.
Never store Quick Cure in the fridge or let it get too cold, because it will become toxic and kill your fish when you do use it.
