Keep your aquatic pets healthy and thriving with SIKEZHAN Methylene Blue Solution — a trusted, broad-spectrum aquarium treatment designed for Koi, Goldfish, Betta, and Turtles.

Why Choose SIKEZHAN Methylene Blue?

• Supports Oxygen Transport: Methylene Blue acts as a powerful oxygen transporter, helping counter the effects of elevated nitrite levels that can convert hemoglobin into methemoglobin — restoring your fish's ability to breathe normally.
• Broad-Spectrum Antiseptic: Lab-tested to help inhibit common external bacterial and fungal microorganisms including Staphylococcus aureus, E. coli, and Candida albicans, keeping your aquatic pets active and healthy.
• New Tank & Quarantine Essential: Perfect for use in new aquariums still establishing their biological filter, or as a quarantine dip for new fish before introducing them to your main tank — helping prevent "New Tank Syndrome" spikes from harming your fish.
• Versatile for Freshwater Species: Suitable for Goldfish, Bettas, Koi, Turtles, and other freshwater inhabitants. Ideal for addressing gasping at the surface, red streaking, or general lethargy associated with poor water quality.
• Two Easy Application Methods: Choose between a full tank treatment or a targeted medicated bath — flexible dosing to suit your situation.
