UP CO2 Bubble Counter Check Valve D-512 – Dual Function In-Line CO2 Control for Planted Tanks

UP CO2 Bubble Counter Check Valve

Take control of your planted tank’s CO₂ delivery with this compact combo device—featuring a bubble counter for visual monitoring and a check valve for system protection.

The UP D-512 system offers two key features in one sleek package. The bubble counter lets users estimate injection rates by counting bubbles per minute, aiding in fine-tuned regulation. The check valve protects against back-siphoning—preventing water from damaging fragile gear like solenoids and regulators. Made from clear plastic, it blends unobtrusively into setups and is easy to clean and mount inside or outside the tank.

Usage Tips:

• Fill the bubble counter with water or colored solution for better bubble visibility
• Use syringe and tubing for easy filling
• Install in-line between regulator and diffuser—ensure check valve’s narrow end faces down
• Always place check valve last before regulator or solenoid

Smart protection meets simple setup—perfect for beginners and experienced aquascapers alike.
