Description

GLA PRO-DS-6 Dual Stage CO2 Regulator (Modular)

The GLA PRO-DS-6 Dual Stage CO2 Regulator is a professional-grade solution designed for advanced planted aquariums and large-scale multi-tank systems. Built for precision, stability, and long-term reliability, it delivers consistent CO2 output without the pressure fluctuations commonly found in single-stage regulators.

Engineered with a fully configured modular manifold, the PRO-DS-6 provides maximum CO2 distribution capacity while maintaining independent control of each aquarium.


Who This Is For

  • Advanced aquascapers and high-demand planted systems
  • Large multi-aquarium setups (6 tanks)
  • Users who require maximum scalability and control

If you are running multiple aquariums and want a fully built, high-capacity CO2 solution with no need for expansion, the PRO-DS-6 is the ideal configuration.


Why Dual Stage Matters

Dual-stage regulators reduce CO2 pressure in two steps, eliminating fluctuations as the cylinder empties. This prevents “end-of-tank dump” and ensures stable, consistent CO2 delivery from full to empty.

  • No end-of-tank pressure spikes
  • Stable working pressure throughout cylinder life
  • Ideal for sensitive and high-demand aquariums

Modular Manifold System

The PRO-DS-6 includes a six-block manifold, allowing you to run up to six aquariums from a single regulator. Each block provides independent control, delivering precise CO2 adjustment for every tank.

  • Six independent CO2 output lines
  • Maximum multi-tank CO2 distribution capacity
  • Independent needle valve control per aquarium
  • Clean, organized system design

How the Manifold System Works:

  • 1 Block → 1 Aquarium
  • 2 Blocks → 2 Aquariums
  • 3 Blocks → 3 Aquariums
  • 4–6 Blocks → Full multi-tank distribution

Each block operates independently, allowing precise CO2 adjustment for every aquarium.


Key Features

  • Dual Stage Regulator: Eliminates pressure fluctuations

FAQ

What is the benefit of dual-stage regulation?
Dual-stage regulators prevent pressure fluctuations as the CO2 cylinder empties, ensuring stable output and eliminating end-of-tank dump.

Can this run multiple aquariums?
Yes. The PRO-DS-6 includes six independently controlled output lines.

Each block provides one CO2 output. This model is configured for up to six aquariums and represents the maximum manifold configuration available.

Can I expand later?
This model is fully configured. Additional expansion is not required, but manifold blocks can be reconfigured if needed.

Is this compatible with other regulators?
No. The modular manifold system is designed specifically for GLA PRO-DS regulators.

    GLA is the best in the game.

    Posted by Seth Armstrong on 8th Sep 2025

    I’d never consider buying anything less than GLA when it comes to a co2 system. I’ve got an older gen that’s 13 years old still working like it was brand new. With my new house and new studio I decided to treat myself and go big. This regulator is the real deal and you’ll know it right away. The quality is evident and execution upon setup is brilliantly designed. It flows co2 like butter to all my diffusers. Flawless design and quality every time from GLA.

    This is one amazing regulator.

    Posted by Albert Hubbard on 10th Aug 2022

    I needed two of these to operate my grow out farm. I try my best at aquascaping but I find I do more dutch style than anything with farming in between. These regulators can feed all my tanks effortlessly. I use inline diffusers for diffusion so maintenance is minimal. Extremely pleased with GLA products.

    Pro level co2 regulator.

    Posted by William Rouse on 2nd Feb 2021

    I ordered this to help feed co2 into 6 farm tanks I have running. This thing is an absolute beast. What I liked most was the quality of the finish of the entire assembly. I know cheap crap when Im holding it, you do not get that feeling with this. Extremely well made through and through. Set up was super easy, about 5 minutes. What took me the longest was mapping out the tubing runs. Solid reliable dual stage co2 regulator. Its even built like a real dual stage. Not like what you see from the rest of the companies. A+ all around GLA.
