Wyin Aqua Mini Smart Sodastream CO₂ In Tank Injection Kit

Ready to see what CO₂ can do for your plants? This WYIN Aqua Mini Smart SodaStream bundle gives you a tidy, reliable way to start injecting CO₂ without committing to a full cylinder. Connect it to a blue SodaStream bottle using the included adapter, set your schedule on the digital controller, and enjoy stronger growth and cleaner lines in your aquascape.

The compact WYIN regulator (W21.8) features an integrated 12 V DC solenoid and bubble counter, plus a programmable timer so you can match CO₂ to your light cycle. Consistent dosing, less faff—your plants get what they need, when they need it.

We’ve added the essentials: a brass SodaStream adapter with control knob, CO₂-resistant 4/6 mm polyurethane hose (choose your length), an inline check valve, and an acrylic diffuser that produces a fine mist for efficient dissolution. To keep you dialled in, the glass drop checker with 15 ml solution lets you monitor CO₂ at a glance.
