GLA DS-Mini Dual Stage CO2 Regulator (Modular)(DIN477)

GLA DS-Mini Dual Stage CO2 Regulator (Modular) (DIN477)

The GLA DS-Mini Dual Stage CO2 Regulator (DIN477) is a compact, professional-grade solution designed for planted aquariums where space, precision, and reliability matter. Built with a dual-stage design, it delivers stable CO2 output without the pressure fluctuations commonly found in single-stage regulators.

This DIN477 version is designed for international CO2 cylinders used in Europe, the UK, Australia, and other regions using DIN-standard valves.

Engineered for flexibility, the DS-Mini features a modular manifold system that allows expansion across multiple aquariums while maintaining independent control of each line.

Who This Is For

• Planted aquarium hobbyists seeking compact, high-performance CO2 control
• Small to medium aquariums
• International users with DIN477 CO2 cylinders

If you want professional CO2 performance in a smaller footprint, the DS-Mini is the ideal solution.

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 to deliver professional performance in a compact form factor. Its smaller size makes it ideal for tight installations while maintaining the stability of a full dual-stage system.

• Compact, space-saving regulator design
• Ideal for aquarium cabinets and smaller setups
• Professional-grade CO2 performance

Modular Manifold System

The DS-Mini can be configured with up to six manifold blocks, allowing you to distribute CO2 to multiple aquariums from a single regulator.

• Expandable from single tank to multi-tank setups
• One block per aquarium
• Independent needle valve control for each tank
• Clean, scalable CO2 system design
