Description
GLA DS-Mini Dual Stage CO2 Regulator (Modular) (DIN477)
The GLA DS-Mini Dual Stage CO2 Regulator (DIN477) is a compact, professional-grade regulator designed for international planted aquarium CO2 installations where space, precision, pressure stability, and modular flexibility are priorities.
Built around GLA’s compact dual-stage regulator architecture, the DS-Mini DIN477 combines two-stage pressure regulation with a modular manifold system that can be configured for one aquarium or expanded to independently control multiple aquariums from a single CO2 cylinder. Each regulator is individually inspected, pressure tested, and leak checked in the USA prior to shipment.

- Regional Options: AU, EU, and UK configurations available at purchase
- Modular Manifold System: Configure the regulator for one aquarium or expand to as many as six independently controlled outputs
- Precision CO2 Adjustment: Each manifold block includes its own precision needle valve
- Integrated Flow Monitoring: Each manifold block includes a bubble counter for convenient visual CO2 monitoring
- Automatic Operation: Integrated solenoid allows CO2 injection to be controlled with a timer or compatible controller
- System Protection: Integrated pressure relief valve provides an additional level of protection
Compact Dual-Stage Pressure Regulation
Dual-stage regulators reduce cylinder pressure through two separate pressure-reduction stages. This architecture is designed to provide increased working-pressure stability as cylinder pressure changes over time and to reduce the likelihood of pressure increases as the CO2 cylinder approaches depletion.
The DS-Mini provides these dual-stage pressure-regulation benefits in a compact form factor designed for planted aquarium installations where equipment space may be limited.
- Two-stage pressure reduction
- Stable and controllable working pressure
- Reduced likelihood of end-of-tank pressure spikes
- Compact architecture for space-conscious installations
International Cylinder Compatibility
The DS-Mini DIN477 is designed for compatible international CO2 cylinder installations and is offered in AU, EU, and UK regional configurations.
CO2 cylinder valve standards may vary by country, cylinder supplier, and cylinder type. Please verify that your local CO2 cylinder connection is compatible with the selected regulator configuration before ordering.
If you are unsure which regional configuration is appropriate for your cylinder, please contact GLA prior to purchase for compatibility assistance.
Precision Control & Automation
Each DS-Mini manifold output includes an independently adjustable precision needle valve and integrated bubble counter, allowing CO2 flow to be tuned separately for each connected aquarium.
The integrated electric solenoid allows CO2 injection to be automatically coordinated with the aquarium photoperiod using a standard timer or compatible controller.
The integrated working-pressure gauge provides a clear visual reference for regulator output pressure. The DS-Mini uses a single gauge dedicated to working pressure rather than separate working-pressure and cylinder-pressure gauges.
Bubble rate should be treated as an aquarium-specific reference rather than a universal measurement of dissolved CO2. Actual CO2 requirements vary with aquarium volume, plant mass, lighting, circulation, diffusion efficiency, and surface agitation.
Modular Manifold System
The DS-Mini modular manifold allows the regulator to grow with your aquarium setup. Select the number of manifold blocks required for your current installation, then add compatible blocks later if additional aquariums are added.
- 1 Block: 1 independently controlled aquarium
- 2 Blocks: 2 independently controlled aquariums
- 3 Blocks: 3 independently controlled aquariums
- 4 Blocks: 4 independently controlled aquariums
- 5 Blocks: 5 independently controlled aquariums
- 6 Blocks: 6 independently controlled aquariums
Each manifold block includes its own precision needle valve and integrated bubble counter, allowing every aquarium to be adjusted independently while sharing a single regulator and CO2 cylinder.

Frequently Asked Questions
What makes the DS-Mini different from the PRO-DS?
Both the DS-Mini and PRO-DS use dual-stage pressure regulation and modular manifold systems. The DS-Mini is designed around a more compact architecture with a 0–60 PSI output range and a single working-pressure gauge. The PRO-DS is GLA’s full-size dual-stage platform with a 0–140 PSI output range, separate cylinder and working-pressure gauges, and expanded capability for higher-pressure applications.
What CO2 cylinders does the DS-Mini DIN477 fit?
The regulator is designed for compatible international DIN477 CO2 cylinder installations. AU, EU, and UK regional configurations are available. Because cylinder valve standards can vary by country and supplier, verify compatibility with your CO2 cylinder before ordering.
Can this regulator be used with a USA CGA-320 CO2 cylinder?
No. This listing is configured for international DIN477-style CO2 cylinder installations. For standard USA CGA-320 cylinders, select the CGA-320 version of the GLA DS-Mini.
Can the DS-Mini run more than one aquarium?
Yes. The DS-Mini can be configured with one to six manifold blocks. Each block provides one independently adjustable CO2 output with its own precision needle valve and bubble counter.
Can I expand the manifold later?
Yes. Compatible manifold blocks can be added as your aquarium system grows. When expanding an existing regulator, be sure to select the manifold generation that matches your regulator because G2 and G3 manifold blocks are not cross-compatible.
What is the benefit of dual-stage regulation?
Dual-stage regulation reduces cylinder pressure through two stages rather than one, providing additional working-pressure stability as cylinder pressure changes and reducing the likelihood of end-of-tank pressure increases.
Does the DS-Mini display CO2 cylinder pressure?
No. The DS-Mini uses a single gauge to monitor regulator working pressure. Aquarists who prefer separate gauges for cylinder pressure and working pressure may consider the GLA PRO-DS platform.
Can I use a diffuser, inline atomizer, or CO2 reactor with the DS-Mini?
Yes. The adjustable 0–60 PSI output supports many planted aquarium CO2 delivery methods when operated within the pressure and flow requirements of the selected diffuser, atomizer, or reactor.
What size aquarium can I use the DS-Mini on?
The DS-Mini is not restricted to a specific aquarium volume. Appropriate CO2 delivery depends on plant demand, lighting, circulation, diffusion method, surface agitation, and overall system configuration. The DS-Mini may be used on both small and large planted aquariums when configured appropriately.
Is the DS-Mini suitable for beginners?
Yes. Dual-stage regulators are not inherently more difficult to operate during normal aquarium use. The DS-Mini is suitable for both beginner and experienced aquarists who want compact dual-stage pressure regulation and future modular expansion capability.
