Description

The V2 Upgrade: Safety and Stability Perfected

This is not a simple revision—it is the ultimate CO₂ solution built for the long term.

  • 100% Guaranteed End-Tank-Dump Prevention: Our advanced Dual Stage Construction ensures a rock-steady output pressure of ~1 PSI stability. As your CO₂ cylinder nears empty, it completely eliminates the final, dangerous pressure surge that kills livestock in single-stage systems.
  • W21.8 International Standard: Built specifically to fit the W21.8 x 14 cylinder thread (also known as DIN477 or BS341) used across Europe, the UK, Australia, New Zealand, and many Asian countries. Simply screw it on and start growing.
  • Medical-Grade Precision Needle Valve: The V2’s new customized solenoid block integrates a medical-grade needle valve. This provides the most precise control available, allowing you to fine-tune your bubble rate with unparalleled accuracy for optimal plant growth.

Features Built for the Elite Aquascaper

  • Next-Generation Solenoid Block: Enjoy a cleaner look, tidier setup, and next-generation reliability from the new fully customized block, perfect for automating your on/off schedule.
  • Modular & Expandable Manifold: Easily scale your system! Add extra manifold blocks (sold separately) to run CO₂ into multiple aquariums or power multiple high-demand diffusers from one central unit.
  • Stainless Steel Dual Gauges: Monitor your system at a glance. Read your cylinder's gas volume and your precise working pressure so you always know when a refill is due.
  • Safe & Cool 12V DC Solenoid: Operates silently with minimal heat, connecting to a universal 100-240V adapter for global compatibility and reliable daily control.
  • Integrated Bubble Counter: Conveniently monitor your dosage and flow rate with a clear visual counter, featuring a built-in check valve to prevent water backflow and protect your regulator.

Built to last for tanks from 5 liters to 5000 liters. Backed by an industry-leading 10-Year Warranty and Lifetime Technical Support. Invest in the V2 and elevate your aquascaping to the professional level.

It is so refreshing to receive such outstanding customer service and genuine attention to detail. From start to finish, the team at Aquascape Shop went above and beyond to ensure everything was perfect. I couldn't be happier with the product I purchased—it exceeded my expectations in both quality and presentation. Their communication, care, and commitment to customer satisfaction were second to none. It's rare to find a business that takes such pride in both its products and its customers. I highly recommend Aquascape Shop and will definitely be purchasing from them again! ⭐⭐⭐⭐⭐

Excellent

Excellent. Worth the initial outlay of cost for me. So consistent. Pressure was set to 41 about 4 weeks ago and hasn't moved at all so very impressed with stability and consistency so far. Excellent price from here as well compared to other online retailers. Shipping was also reasonable quick to east coast Australia.
