Precision CO2 Monitoring for Thriving Aquariums

Crafted from high-clarity glass with a sleek water-drop shape, this CO2 drop checker ensures accurate, real-time monitoring for planted tanks. The corrosion-resistant design features a built-in suction cup for secure attachment to aquarium walls, providing unobstructed viewing angles.

Professional-grade reagent solution changes color based on dissolved CO2 levels, allowing instant visual assessment without electrical components. Ideal for high-tech planted tanks, shrimp habitats, and Dutch aquascapes requiring stable carbon dioxide levels between 20-30 ppm.

Engineered with a spill-proof internal chamber and ultra-fine air vents to prevent false readings. The compact 4cm diameter design blends seamlessly into nano tanks and large setups alike. Includes pH-sensitive fluid optimized for both freshwater and low-salinity brackish environments.

Durable borosilicate glass resists algae growth and maintains optical clarity long-term. Essential tool for preventing CO2 overdosing during pressurized system use or verifying natural carbon levels in Walstad-method aquariums.

Premium packaging with shock-absorbent foam ensures international shipping safety. Bulk order discounts available for aquatic retailers and commercial fish farms requiring fleet-wide monitoring solutions.
