Key Features & Benefits

• Nano-friendly design — compact footprint makes it ideal for small tanks and tight setups

• Easy to install & use — screw in the CO₂ cartridge, attach tubing and diffuser, and you're ready to dose

• Steady bubble rate — in tests running at ~1 bubble every 5 seconds (for ~8 hours/day), each 16 g cartridge lasted ~35 days

• Expandable — optional add-ons like bubble counters, solenoids, and controllers can upgrade your setup
  

Ideal Applications

• Nano tanks (e.g. ≤ 30 L)

• Aquascapes requiring gentle CO₂ injection

• Users seeking a low-maintenance entry point into pressurized CO₂ for plants

Usage Tips & Considerations

• Always use food-grade CO₂ cartridges with compatible threading.

• Begin with lower bubble rates and adjust upward slowly, observing plant and fish response.

• Monitor cartridge levels — once pressure drops, swap to a fresh one.

• For longer tanks or more demanding CO₂ needs, consider pairing with a dual-gauge regulator or solenoid upgrade.
