GLA DS-Mini Dual Stage CO2 System (Modular)
The GLA DS-Mini Dual Stage CO2 System is a compact, professional-grade solution designed for planted aquariums where space, precision, and reliability matter. Built around our dual-stage regulator platform, it delivers stable CO2 output without pressure fluctuations, even as your cylinder empties.
Combining premium performance with a space-efficient footprint, the DS-Mini is ideal for aquarists who want the benefits of a dual-stage system in a smaller, space-efficient design.
Who This Is For
- Planted aquarium hobbyists seeking premium performance in a compact setup
- Small to medium aquariums
- Users who want dual-stage stability without a full-size regulator
If you want professional CO2 control in a streamlined, space-saving system, the DS-Mini is the ideal solution.
What’s Included
- GLA DS-Mini Dual Stage CO2 Regulator with modular manifold (1 block, expandable)
- 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 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
- Improved reliability for planted aquariums
Compact Dual Stage Design
The DS-Mini is engineered for aquarists who need high performance in a smaller footprint. Its compact design makes it ideal for tight installations while maintaining the stability and precision of a full dual-stage system.
- Space-efficient regulator design
- Ideal for cabinets and smaller installations
- Maintains professional-grade CO2 performance
Modular Manifold System
The DS-Mini includes a single-block manifold for one aquarium and can be expanded with additional blocks as your system grows.
- Single aquarium setup (expandable)
- Add blocks for multi-tank CO2 distribution
- Independent control for each aquarium
How the Manifold System Works:
- 1 Block → 1 Aquarium
- 2 Blocks → 2 Aquariums
- 3 Blocks → 3 Aquariums
- 4+ Blocks → Expand as needed
Each block provides independent CO2 control for each aquarium.

What a truly wonderful co2 system.
After a nightmare scenario with a previous vendor I was advised to reach out to GLA. Best decision ever! Customer service was unbelievable and I feel like family now.

High quality and easy to expand manifold.
Very pleased with GLA service and more-so the adaptability of this unit. I have had this system just over one year but I have a new tank. So I come to GLA to expand buy adding a manifold. After installing this system is just fantastic. GLA is the best.
