Made in Mainland China.

🐠 Step 1: SIKEZHAN Methylene Blue — Disease Treatment

Professional-grade Methylene Blue targets common aquarium threats quickly and effectively:

• Targets Ich (White Spot), Fungus (Saprolegnia), Velvet & Tail Rot — a frontline defence for freshwater and saltwater tanks
• New Fish Quarantine Bath — safely disinfect incoming fish before introducing them to your main tank
• Egg Disinfection — protects fish eggs from fungal growth to boost hatch rates
• Broad Compatibility — safe for Goldfish, Bettas, Guppies, Tetras, Cichlids, and more

Usage: Add 5–10ml per 100L of water. Note: May temporarily tint silicone seals and tank decorations blue.

💧 Step 2: Nitrifying Bacteria — Ecological Recovery

After treatment, restore your tank's biological balance fast with high-concentration live nitrifying bacteria:

• Breaks Down Ammonia & Nitrite — prevents dangerous "New Tank Syndrome" and keeps water chemistry safe
• Crystal Clear Water — decomposes organic waste, uneaten food, and cloudiness
• Post-Medication Bio-Repair — essential for rebuilding healthy bacteria colonies after antiseptic use
• Works in Freshwater & Saltwater Aquariums

Usage: Shake well. Add 10ml per 100L weekly or after each water change.

🔄 The Perfect "Treat & Recover" Cycle

1. Fish shows signs of illness → Apply Methylene Blue
2. Perform a partial water change to clear medication residue
3. Add Nitrifying Bacteria → Restore eco-balance and keep water healthy

Together, these two products create a self-sustaining cycle of aquarium health — no guesswork, no compromise.

Frequently Asked Questions

Q: Can I use Methylene Blue and Nitrifying Bacteria at the same time in my aquarium?

A: No — it is best to use them sequentially. First, apply the Methylene Blue treatment to address Ich, fungus, or other concerns. Then, after completing the treatment and performing a partial water change, add the Nitrifying Bacteria to restore the beneficial bacteria colonies that may have been disrupted during the treatment phase.

Q: Is this aquarium care kit safe for Betta fish and Goldfish?

A: Yes! This kit is formulated to be safe for a wide variety of freshwater species, including Betta fish, Goldfish, Guppies, Tetras, and Cichlids, as well as saltwater aquariums. Always follow the recommended dosage on the label for best results.

Q: Will Methylene Blue stain my aquarium decorations or equipment?

A: Methylene Blue may temporarily tint silicone seals, porous decorations, and plastic ornaments blue. This is a cosmetic effect and does not affect the health of your fish. Most staining fades after water changes and normal filtration activity.

Q: How often should I add Nitrifying Bacteria to my tank?

A: For established tanks, add 10ml per 100L of water weekly or after each water change. For new tank cycling or post-medication recovery, more frequent dosing may be beneficial until the aquarium's biological filter is fully established.
