NT Labs Aqua Methylene Blue 100ml

This concentrated liquid treatment is designed to help aquarists tackle common external infections in fish and eggs with confidence. Methylene Blue has broad-spectrum action against bacterial, fungal and some external protozoan problems, making it a smart go-to for sick fish, fry and vulnerable eggs in both tropical and coldwater systems. It�s safe to use in quarantine tanks, treatment baths or directly in aquarium water (including during transport), and can even be applied undiluted to wounds for targeted care. Proper dosing helps protect your stock while you work to restore water quality and fish health. Always follow usage instructions, maintain filtration (remove carbon during treatment) and perform a water change after treatment to reset your tank environment.
