How to Use the Chihiros Nano CO₂ Diffuser

Soak the diffuser in clean water for at least 30 minutes before first use.
Connect CO₂ tubing (4/6 mm) securely to the diffuser inlet.
Place the diffuser near the substrate or area of good water circulation.
Start CO₂ injection and check for uniform micro-bubble output.
Clean periodically to maintain high diffusion efficiency.

Care & Maintenance Tips

Soak the ceramic disc in bleach solution (1:10) for 30 minutes to remove buildup, then rinse thoroughly.
Handle gently — glass components are fragile.
Use with a bubble counter to monitor injection rates.
For best results, pair with Chihiros CO₂ Regulator and Chihiros CO₂ Diffuser Stand.
Replace the diffuser disc if CO₂ flow becomes uneven or reduced.
