Wyin Aqua Quick Plug CO₂ Bubble Counter

The makes monitoring your planted tank’s CO₂ system simple, reliable, and stylish.

Crafted from gunmetal aluminum alloy, this bubble counter is built to last while adding a sleek touch to your aquarium setup. The transparent viewing chamber gives you a clear view of the bubble rate, making CO₂ adjustments straightforward and accurate.

With its Quick-Plug design, connecting your 4/6mm tubing takes just seconds, while the easy-refill twist system lets you top up the chamber with water whenever needed. Unlike basic bubble counters, this model comes with a precision-built check valve to stop water from flowing back into your regulator — giving you peace of mind and protecting your equipment.

The included removable metal pin gives you flexibility: use it inline as a standard bubble counter, or connect it directly with other Quick-Plug compatible devices. Whether you’re just starting with CO₂ injection or upgrading your setup, this is a professional-grade solution trusted by aquascapers. What’s Included
