Q: Is this Methylene Blue treatment safe for tropical freshwater and saltwater fish?

A: Yes — this pharmaceutical-grade solution is suitable for use in both freshwater and marine (saltwater) aquariums. It is compatible with all tropical fish, goldfish, bettas, angelfish, and other common aquarium species. Always follow dosage instructions (2ml per 10 litres) and remove activated carbon from your filter during treatment.

Q: How long does a bottle of this aquarium Methylene Blue last?

A: This product has a shelf life of up to 2 years when stored correctly in a cool, dark location away from direct sunlight. The concentrated formula means a little goes a long way — dosage is just 2ml per 10 litres of tank water.

Q: Will Methylene Blue stain my aquarium or decorations?

A: Methylene Blue is a blue dye and may temporarily tint your aquarium water blue. It can also stain silicone sealant, plastic decorations, or light-coloured substrates. We recommend treating fish in a separate quarantine tank where possible to avoid staining your main display aquarium.
