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.

Customer Reviews

Very nice quality stuff from GLA.
I purchased this to replace my co2art regulator because the needle valve and solenoid were so unreliable. I was always adjusting my co2 to the point it was giving me anxiety. After a month of using GLA co2 systems its been just terrific. A breath of fresh air and I literally feel like I can breath again. My co2 is more stable now by looking at the data from my Apex controller. You will see cheaper options, but GLA is the best in the industry in co2. The service and reliability is worth every penny. Thank you GLA.

Quality co2 system through and through.
Wonderful experiance with GLA. Ive been back already for other parts and could not be happier. This system is much nicer than any other system I have owned. GLA thought of everything with this compact co2 system. Its dual stage, has two working opposing piston diaphragms. The needle valve is whats super nice, you get such a smooth linear motion with your bubble counter. You can control the flow with ease and this thing is always steady in its feed. Great price too!

This is a superb co2 system.
After spending the week trying to decide which system to get I decided on this. It was a little more than the Gro kit, but worth it. This one is modular. I can feed two tanks or more with this one system. GLA provides a shiny nice cylinder,tubing,check valve and seal. All you have to do is add some sort of diffuser. I opted for the GLA co2 reactor. I gotta say, all the GLA gear under my tank is nothing short of stellar. I wish I had a glass cabinet so you could see the beauty in it all. I added an additional manifold so I could feed my 2 tanks at one time and I love how its all so effortlessly working everyday. I dont do anything ever but clean my bubble counters every few weeks. GLA does a stand up job providing superior essentials. Extremely helpful every step of the way and was happy to post this review for GLA. I would have given more stars had I had the option.

Its awesome!
Really enjoying this co2 system. I chose this kit because it was the do everything regulator. Im not sure why they dont mention it or maybe I missed it but you can use this regulator on any cylinder type. This kit comes with a 5lb cylinder but I will be getting stationed overseas soon and I will definitely be bring this with me. Only problem is in Guam I will need to use paintball or disposable. Either way this GLA kit has been amazing!

Fantastic!
I love this system and my experience with GLA. Not only is this co2 system super nice, its well priced and feature rich which I like. Its super compact and fits just right under my 90p. Unreal how they are able to pack dual stage technology in such a small package.
-
I love this co2 system.
I think this is GLA's best bargain in terms of a co2 system. You get dual stage co2 regulator, modular manifolds and a beautiful new cylinder. You will need to add a co2 diffuser but thats all your going to need. Comes with easy to follow instructions and they even have videos if you need them. I did both and could not be more pleased. If your reading this and are budget conscious, this is the one!
