Co2 Art PRO-SE Series - Aquarium CO2 Dual Stage Regulator with Integrated Solenoid is backordered and will ship as soon as it is back in stock.
Engineered for precision, safety, and long-term reliability.
The CO₂Art PRO-SE Series Dual Stage Regulator delivers ultra-stable CO₂ output for planted aquariums, protecting your livestock while giving you total control over injection.
Description
Description
If you want vibrant growth without babysitting your bubble rate, this is the one. The PRO-SE’s dual-stage design keeps output pressure consistent as the cylinder empties, helping prevent end-of-tank pressure spikes and keeping livestock comfortable while plants feast.
Setup is delightfully simple: plug in the safe 12 V DC solenoid to your timer, dial in the ultra-precise needle valve, and watch the included bubble counter do its thing (with built-in check valve to stop backflow). Twin gauges make it easy to read cylinder and working pressure at a glance.
Performance is tuned for planted tanks big and small. With adjustable working pressure up, it pairs beautifully with ceramic diffusers, inline atomisers, or reactors for crisp, consistent CO₂ delivery and that coveted “glass-clear, pearling at lights-on” look.
Most importantly for local hobbyists: this is the W21.8 thread — the AU/NZ Type 30 / EU standard. In short, it fits standard refillable CO₂ cylinders across AU, NZ, and Europe. No adapters, no guesswork, just connect and scape.
Key Features
- Dual-stage construction for stable output (helps prevent end-of-tank dump)
- Integrated 12 V DC solenoid for timer-controlled dosing
- Ultra-precise needle valve for smooth, repeatable adjustments
- Bubble counter with in-line check valve included
- Dual gauges: cylinder (high) + working (low) pressure
- Adjustable working pressure up to 40 PSI (≈ 3 Bar)
- Thread: W21.8 / Type 30 / BS341 No. 8 / DIN 477 (AU/NZ/EU standard)
- 5-year CO₂Art manufacturer warranty
Tip: Start CO₂ 1–2 hours before lights on, and aim for a gentle lime-green drop checker by peak photoperiod.
Built for aquascapers who want function and form in perfect harmony.
