GLA PRO-DS Dual Stage CO2 System (Modular)

GLA PRO-DS Dual Stage CO2 System (Modular)

The GLA PRO-DS CO2 System is a complete, professional-grade solution designed for serious planted aquariums. Built around our dual-stage regulator platform, this system delivers exceptional pressure stability, precision control, and long-term reliability.

Designed for aquarists who demand consistent performance, the PRO-DS eliminates end-of-tank pressure fluctuations and provides stable CO2 delivery throughout the entire life of your cylinder.

Who This Is For

• Advanced aquascapers and high-demand planted tanks
• Multi-aquarium setups
• Users who want maximum stability and long-term reliability

If you are looking for the highest level of CO2 control and a system that can grow with your setup, the PRO-DS is the ideal solution.

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 steps, eliminating the fluctuations commonly seen in single-stage regulators as the cylinder empties. This prevents “end-of-tank dump” and ensures stable CO2 output for consistent plant growth.

• No end-of-tank pressure spikes
• Consistent working pressure from full to empty
• Improved stability for sensitive or high-tech 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

Key Features

• Dual Stage Regulator: Eliminates pressure fluctuations and ensures stable output
• Modular Manifold: Expandable CO2 distribution system
• Precision Needle Valve: Micro-adjustment for accurate CO2 dosing

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?
This system is designed for users who want the highest level of control and long-term performance. Beginners may also use it, but simpler systems are available.
