Methylene Blue Fish Care is a versatile aquarium treatment commonly used by fish keepers, breeders, hatcheries, and ornamental fish farms to help manage fungal infections, White Spot (ICH), and other external fish health problems. It is particularly useful for treating fish eggs, fry, and freshwater aquarium fish when used according to the recommended dosage.

How to Use
Always follow the recommended dosage instructions on the product packaging. The correct dosage can vary depending on the concentration of the solution and the size of the aquarium or treatment container.
For fish that require medication, a separate hospital or quarantine tank is generally recommended. Remove activated carbon or other chemical filtration media during treatment, as they may reduce the effectiveness of the treatment.
Methylene Blue can stain aquarium decorations, silicone, and other porous materials, so using a separate treatment container can help prevent unwanted staining.
Important Usage Note
Use Methylene Blue only according to the recommended dosage. Avoid overdosing and carefully observe fish during treatment. When possible, treat fish in a separate hospital or quarantine tank to avoid staining your main aquarium and to protect beneficial biological filtration.
