Nano tanks (e.g. ≤ 30 L)
Aquascapes requiring gentle CO₂ injection
Users seeking a low-maintenance entry point into pressurized CO₂ for plants
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.
