GLA PRO-CO2 Reactor 5L – High-Efficiency CO2 Dissolution for Planted Aquariums
The GLA PRO-CO2 Reactor 5L is designed for high-efficiency CO2 dissolution in demanding planted aquarium systems. Built for high-tech aquascapes and larger planted aquariums, this reactor helps deliver stable, consistent CO2 saturation with minimal gas waste.
Key Features:
- 5L High-Capacity Reactor Chamber: Designed for high-flow filtration systems while maintaining stable CO2 saturation throughout the aquarium.
- Professional Acrylic Construction: Crystal-clear acrylic body designed for durability and long-term performance (19" tall × 6" diameter).
- Whirlpool Diffusion System: Internal vortex chamber promotes efficient CO2 mixing and dissolution before water returns to the aquarium.
- Universal Tubing Compatibility: Supports 12/16mm, 16/22mm, and 20/25mm tubing for compatibility with most canister filters and external pumps.
- Quiet, Bubble-Free Operation: Reduces visible microbubbles and CO2 noise commonly associated with traditional diffusers.
- Efficient CO2 Utilization: Helps reduce CO2 loss while improving overall system stability.
- Maintenance-Friendly Design: Wide body and removable top allow easier cleaning and access to internal components.
Installation & Functionality:
- Install the reactor inline with your canister filter return/output line.
- Connect CO2 tubing using the integrated Speedfit connection with built-in on/off valve.
- The internal vortex chamber creates a high-flow mixing environment that improves CO2 dissolution efficiency.
- Adjust CO2 injection according to the needs of your planted aquarium.
Why Choose a CO2 Reactor?
- Improved CO2 Dissolution: Efficient CO2 absorption with reduced gas waste.
- Ideal for Larger Aquariums: Well-suited for medium to large planted aquariums where higher CO2 demand exists.
- Cleaner Display Appearance: Inline reactor design minimizes visible equipment and microbubbles inside the aquarium.
- No Additional Power Required: Operates using existing filtration flow.
The GLA PRO-CO2 Reactor 5L is designed for aquascapers seeking stable, efficient CO2 delivery in larger planted aquarium systems.

Without doubt the best co2 reactor in the game.
This is a huge reactor so be sure to read the specs. I suggest adding 2” to what they list due to the hose connections. It’s a large volume unit where zero co2 escapes, zero waste! My tank is on point daily with co2. Plants pearling and my plumbing looks rad!

Best co2 reactor on the market.
I’m not novice to using co2 reactors as I’ve got a few I’ve used. This GLA reactor is near perfect. I’d rate it 5 stars if it came with a check valve for the co2 tubing. Other than that it’s perfect. Very well made design without a drop of co2 escaping. I have mine hooked up to a dedicated pump made by Iwaki and it moves water like a beast at 1800gph. Reactor performs perfectly everyday.

Absolute CO2 excellence.
I own quite a bit of equipment from GLA and every time it’s top quality stuff. Their service is also unmatched. I’m louding service because they have an incredible text message service. They provide photos and videos of whatever you might need. Really great people to work with. But back to this reactor, it’s a really good reactor. Comes with a bunch of hose fittings to choose from and they even include a whole dang roll of Teflon tape lol. It took me about two days to dial in to perfection. Tank is crystal clear and void of the 7-Up look from traditional diffusers. Now the only visible bubbles are my plants peeling like mad.

Outstanding reactor and premium customer service.
The reactir is absolutely outstanding and GLA’s customer service is amazing. They should write a book on how to setup and install co2 systems on very large tanks. My tank is 230g in size and they helped me from start to finish and I could not be more pleased. Everything was shipped for free. The service was free and worth every penny in my investment in a full GLA CO2 system. Everything works like a top. Thank you GLA.

It’s an absolute unit of a co2 reactor.
You really don’t get the size of how big it is until it arrives, it’s huge! Pro tip: I installed the GLA inline at the top to atomize co2 prior to it entering the reactor and it works INCREDIBLY well. Then! I used the original co2 inlet port for my GLA Nectar AIO Dosing port. Injecting fertilizer into a virtual mixing vessel prior to entering the tank. This was GLA’s advice and I could not be happier. What a work of art this system has turned out to be.

GLA is the best in aquascaping gear.
Been a customer with GLA since 2008. Still using my old co2 kit from then and now upgraded to this co2 reactor. It’s been an amazing unit and works really well on my 120g tank. It’s a huge reactor so it’s been able to handle the high flow from my pump and large amount of co2. Thanks GLA for continuing to put out great products.
-
Very pleased with this co2 reactor.
Super efficient and high quality reactor. Using this on my 90g has been an absolute success. Plants are happy and my drop checker is a perfect shade of green/yellow. Yes I keep my co2 on the high side but my tank is happy!
-
Beast mode has been activated!
The photo does no justice with this reactor. It’s massive and works perfectly! Co2 levels are stable and stay steady everyday. I have my co2 on a ph controller so my levels are dialed into perfection. High quality unit that freaking works! A++
-
This thing rocks!
This is what I’ve wanted since ditching my Cerges reactor. That thing was a nightmare and an absolute abortion of a design. With this it’s just super easy to use and I don’t ever mess with it. My co2 is stable and always puts my drop checker near the yellow zone in short time.

GLA the best in co2 equipment.
I use GLA equipment for years and never a problem. GLA customer support always very kind and supportive anytime I have a question on anything. Really love their text-message support system which was just incredible at my success with my aquascape. This will be my 2nd time entering IAPLC contest and already feeling positive. Love this reactor.
