Simply attach it to your tank wall with the included suction cup and monitor your CO2 in real-time.

Made from durable, high-quality glass, this checker provides stable and reliable readings. The convenient pre-mixed solution eliminates the need to measure ratios — just use it directly from the bottle. Perfect for planted tank enthusiasts who want professional-grade CO2 monitoring without the complexity.
