Acrylic CO2 Diffuser & Bubble Counter for Aquarium Plants

Acrylic Transparent CO2 Diffuser & Bubble Counter for Aquarium Plants

Give your aquatic plants the carbon dioxide they need to thrive! This crystal-clear acrylic CO2 diffuser and bubble counter is engineered for planted aquariums, delivering a steady, even stream of fine CO2 bubbles that supercharge photosynthesis and encourage lush, healthy water grass growth. Whether you're a beginner aquarist or a seasoned planted-tank enthusiast, this compact diffuser is an easy and effective upgrade for your setup.

Key Features

• Nanometer Ceramic Diffusion Disc: Premium nano-ceramic material breaks CO2 into ultra-fine, evenly distributed micro-bubbles for maximum absorption by aquatic plants.
• Built-in Bubble Counter: Monitor your CO2 output at a glance — simply observe the bubble rate in the water-filled chamber to dial in the perfect flow for your tank size.
• Integrated Mini Check Valve: The concealed check valve delivers stable, consistent performance and prevents water from flowing back into your CO2 supply line.
• Backflow-Resistant Design: Stable acrylic structure minimises the risk of backflow, keeping your CO2 system running safely and efficiently.
• Suction Cup Included: The strong suction cup mounts the diffuser securely to the interior wall of your fish tank — no tools required.
• Crystal-Clear Acrylic Body: Transparent construction lets you see the CO2 bubbles and water level inside the device at all times.

How to Use

1. Connect the diffuser to your CO2 regulator using a standard CO2 airline tube, then position it in the centre of your fish tank using the suction cup.
2. Before connecting the airline, pour a small amount of water into the elbow chamber of the diffuser. Once the tube is connected, air pressure will push the water into the counting cavity, activating the bubble-counting function.
3. Slowly open the fine-tune valve on your CO2 pressure-reducing regulator and observe the bubble rate in the diffuser chamber to confirm the amount of CO2 being added. Adjust the flow to suit the volume of your aquarium.

Frequently Asked Questions

Q: Is this CO2 diffuser compatible with standard CO2 airline tubing?

A: Yes, this aquarium CO2 diffuser is designed to connect with standard CO2 airline tubing used with most CO2 regulators and pressurised CO2 systems. Simply attach your existing tubing to the inlet port of the diffuser.

Q: How do I activate the bubble counter function?

A: Before connecting the airline tube, pour a small amount of water into the elbow chamber of the diffuser. Once you connect the tube and open your CO2 regulator, air pressure pushes the water into the counting cavity, allowing you to monitor the bubble rate and adjust CO2 flow accordingly.

Q: What size aquarium is this CO2 diffuser suitable for?

A: This compact diffuser (approx. 8.5 cm × 3.5 cm) is well-suited to small and medium planted aquariums. Adjust the CO2 flow rate on your regulator based on the volume and plant density of your specific tank for best results.

Q: Does this diffuser include a check valve to prevent backflow?

A: Yes, an integrated mini check valve is built directly into the diffuser body. This helps maintain stable CO2 flow and prevents water from travelling back up into your CO2 supply line.
