How It Works

Methylene Blue acts as a powerful oxygen-transport support agent. When elevated nitrite levels in aquarium water interfere with a fish's ability to carry oxygen in its bloodstream, this solution helps restore normal oxygen-carrying function — keeping fish active and alert. It also provides broad-spectrum antiseptic support, helping to inhibit the growth of harmful external bacteria and fungi that can affect aquarium inhabitants.

Key Benefits

• Nitrite Defense: Specially formulated to combat the effects of high nitrite levels caused by unstable filtration or new tank cycling. Helps restore the fish's oxygen transport function, addressing lethargy, surface gasping, and red streaking linked to poor water quality.
• Broad-Spectrum Antiseptic: Lab-tested to inhibit common external bacterial and fungal microorganisms including Staphylococcus aureus, E. coli, and Candida albicans, keeping your aquatic pets healthy and active.
• New Tank & Quarantine Support: Essential for new aquarium setups or quarantine tanks. Acts as a protective buffer when your biological filter is not yet fully established, helping to prevent sudden ammonia/nitrite spikes from harming fish.
• Versatile Application: Suitable for a wide range of freshwater inhabitants including Goldfish, Bettas, Koi, and freshwater turtles.
• Quarantine Dip Aid: Perfect for dipping new fish before introducing them to your main display tank, reducing the risk of introducing pathogens.

Two Easy Application Methods

1. Whole Tank Treatment: Add 10ml per 100L of water. Repeat every 3 days for 2–3 applications. For best results, raise water temperature to 30°C. Recommend performing a 30% water change before use.
2. Medicated Bath / Dip: Add 2ml per 10L of water in a separate container. Soak fish for 2–3 minutes. Ensure water temperature matches your main tank to avoid temperature shock.
