Description
GLA PRO-DS Dual Stage CO2 System (Modular)
The GLA PRO-DS CO2 System is a premium modular planted aquarium CO2 system designed for aquarists seeking exceptional pressure stability, scalability, and long-term flexibility. Built around our dual-stage regulator platform, the PRO-DS delivers precise and dependable CO2 control for a wide range of planted aquarium systems.
Designed for aquarists who value long-term consistency and modular expandability, the PRO-DS utilizes dual-stage pressure reduction to help maintain stable CO2 output as cylinder pressure changes over time while reducing the likelihood of end-of-tank pressure spikes.
Who This Is For
- Beginner or advanced hobbyists seeking premium dual-stage architecture
- Expandable planted aquarium systems
- Multi-aquarium CO2 distribution
- Aquarists who value modular scalability and long-term flexibility
The PRO-DS is designed for hobbyists who want a premium modular CO2 platform capable of supporting both current and future planted aquarium systems.
What’s Included
- GLA PRO-DS Dual Stage CO2 Regulator with modular manifold (expandable)(configured as selected)
- 5 lb aluminum CO2 cylinder (ships empty)
- CO2-resistant aquarium tubing (10 feet)
- GLA OEM CO2 tank seal
Why Dual Stage Matters
Dual-stage regulators reduce CO2 pressure in two stages, helping provide increased pressure stability as cylinder pressure changes over time while reducing the likelihood of end-of-tank pressure spikes.
- Reduced likelihood of end-of-tank pressure spikes
- Stable working pressure throughout cylinder life
- Excellent long-term consistency for planted aquariums
Modular Manifold System
The PRO-DS features a fully modular manifold system, allowing you to expand CO2 distribution to multiple aquariums using a single regulator. Additional manifold blocks can be added or removed as your setup evolves.
- Start with a single aquarium and expand to multiple tanks as needed
- Independent control for each aquarium
- Clean, scalable system design
How the Manifold System Works:
- 1 Block → 1 Aquarium
- 2 Blocks → 2 Aquariums
- 3 Blocks → 3 Aquariums
- 4+ Blocks → Expand as needed (up to 6 blocks)
Each block includes its own precision needle valve, allowing independent CO2 control for each aquarium.

FAQ
What is the benefit of dual-stage regulation?
Dual-stage regulators prevent pressure fluctuations as the CO2 cylinder empties, providing consistent output and eliminating end-of-tank dump.
Can this run multiple aquariums?
Yes. The PRO-DS system uses a modular manifold design that allows you to expand CO2 distribution to multiple aquariums.
Each “block” on the manifold represents one independently controlled CO2 output. When selecting your configuration above, simply choose the number of blocks based on how many aquariums you plan to run.
- 1 block = 1 aquarium
- 2 blocks = 2 aquariums
- 3 blocks = 3 aquariums, and so on
For example, if you are running three planted tanks, you would select a 3-block manifold. Additional blocks can be added later if your setup expands.
Does the CO2 tank come filled?
No. The cylinder ships empty and must be filled at a local supplier.
Is this suitable for beginners?
Yes. While the PRO-DS offers premium dual-stage architecture and modular expandability, it may be used successfully by both beginner and advanced planted aquarium hobbyists. Many aquarists choose modular dual-stage systems specifically for their long-term flexibility and future scalability.

Love it!
Its hard to find a place that not only specializes in aquscaping but also co2 at the same time. GLA is world renowned for aquarium co2 systems. Not only that but I needed a complete co2 system, cylinder and all. GLA carries not only all the parts needed out of the box but also the highest quality. You get what you pay for with GLA. Superb quality and performance from your purchase. Im absolutely thrilled with my GLA co2 system.

Wow!
This is my 3rd co2 system and my first from GLA. All I can say is wow! Photos do not do there systems any justice. Its when you hold one in your hand and get it working you see the dream come alive. This co2 system surpasses all my previous co2 systems on every level. Everything about the installation was so smooth, literally smooth like butter. All the knobs and adjustments just felt so smooth when adjusting things into place. It was very easy to install and is by far the sexiest pice of aquarium equipment I own. You cant go wrong with GLA. They are indeed the industry standard. A+
