Pro-Elite Series V2 – The Most Advanced Aquarium Dual Stage CO2 Regulator ”NEW”

Built for aquariums from 5 L to 5,000 L, this dual-stage CO2 regulator for aquariums pairs safety with fine precision. The two-stage architecture prevents end-tank dump as cylinder pressure falls, so your plants get a consistent bubble rate day after day. Meanwhile, the custom solenoid block integrates a medical-grade needle valve and a bubble counter, making setup cleaner, tidier, and far more accurate. As your scape grows, simply snap on more manifold blocks to feed extra diffusers or additional tanks.

Features & Benefits

• True Dual-Stage Stability: Minimizes output creep and eliminates end-tank dump for steady CO2 delivery.

• 12 V DC Solenoid (Safe & Cool): Low-heat, low-voltage coil for reliable daily on/off control (100–240 V adapter included).

• Adjustable Working Pressure: Fine-tune up to 5 bar for atomizers, inline diffusers, and reactors.

• Stainless Dual Gauges: Read cylinder (tank) and working pressure at a glance.

• Integrated Precision Needle Valve: Medical-grade metering for ultra-stable bubble rates.

• Bubble Counter + Check Valve: Visual dosing with built-in backflow protection.

• Expandable Manifold Block: Add two, three, or more outlets—scale your system without replacing the regulator.

• Thread: CGA320 to match your cylinder.

• Any Cylinder Size: Thanks to the dual-stage design, it’s compatible from small paintball canisters to large bottles.

How to Use

1. Mount the regulator to your CO2 cylinder (choose W21.8×14/DIN477/BS341 or CGA320 accordingly).

2. Set initial working pressure; power the 12 V DC solenoid via the included 100–240 V adapter.

3. Dial in the needle valve for your target bubble rate and confirm via the bubble counter.

4. If you run multiple tanks or diffusers, attach additional manifold blocks and repeat the trim.

Why It’s Different

Most regulators make you choose between precision and scalability. This one delivers both. Start with a single-outlet, nano-friendly setup; then, as your aquascaping ambitions expand, bolt on extra outlets in minutes—no tools, no guesswork, no new regulator. It’s modular CO2, done right.

Ideal For

• High-tech planted aquariums (atomizers/inline diffusers)

• Multi-tank racks and large displays 500 L+

• Hobbyists who want future-proof, end-tank-dump-proof gear
