Description

GLA PRO-CO2 Reactor 5L – Maximum CO2 Saturation for Nature Aquariums

The GLA PRO-CO2 Reactor 5L is engineered for unmatched CO2 dissolution, delivering maximum efficiency with virtually zero waste. Built for serious aquascapers and high-tech planted aquariums, this reactor ensures stable, high-level CO2 saturation to support vibrant, healthy, and fast-growing aquatic plants.

Key Features:

  • 5L High-Capacity Reactor Chamber: Designed to handle high-flow filtration systems while maintaining consistent CO2 saturation throughout the water column.
  • Precision-Designed in the USA: Constructed from professional-grade, crystal-clear acrylic for durability and long-term performance (19" tall × 6" diameter).
  • Whirlpool Diffusion System: The internal vortex chamber creates a high-flow whirlpool effect, ensuring complete CO2 absorption before water returns to your aquarium.
  • Universal Tubing Compatibility: Supports 12/16mm, 16/22mm, and 20/25mm tubing for seamless integration with most canister filters and external pumps.
  • Quiet, Bubble-Free Operation: Eliminates microbubbles and CO2 noise common with diffusers—ideal for display tanks and living spaces.
  • Maximum CO2 Efficiency: Reduces CO2 loss and ensures every bubble is fully dissolved, saving gas and improving stability.
  • Maintenance-Friendly Design: Wide body and removable top allow for quick cleaning and access to internal components.

Installation & Functionality:

  1. Connect the reactor inline with your canister filter’s return/output line.
  2. Attach CO2 tubing using the built-in Speedfit connection—a secure, tool-free fitting with an integrated on/off valve for precise CO2 control.
  3. Allow the vortex system to create a high-energy mixing environment that fully dissolves CO2 before water re-enters the tank.
  4. Adjust your CO2 rate to match the demands of your planted aquarium for optimal growth and stability.

Why Choose a GLA CO2 Reactor?

  • Professional-Grade Performance: Built for high-demand aquascapes requiring stable and high CO2 levels.
  • Enhanced Plant Growth: Provides consistent, fully saturated CO2 delivery that drives lush growth and stronger coloration.
  • Ideal for Larger Tanks: Perfect for medium to large nature aquariums where diffusers cannot keep up with CO2 demand.
  • Energy Efficient: Works flawlessly with existing filtration—no additional power required.

Built for aquascapers who demand uncompromising performance, the GLA PRO-CO2 Reactor delivers precise CO2 control, maximum dissolution efficiency, and superior plant health for the most demanding planted tanks.

    Huge improvement with the new reactor.

    Posted by Nathan Elkstrom on 30th Mar 2025

    Hooked it up this morning after removing my older GLA acrylic reactor and what an upgrade! First, the .45* elbow is a game changer compared to the old 90* elbow. My flow going into the reactor is stronger and I have more pressure building up within the reactor. It’s been about 6hrs now and it’s been awesome. With the old acrylic reactor by now I’d have a gigantic gas pocket. Right now I have a negligible gas pocket which I totally expect. But I’m guessing the larger volume and increased flow and pressure are helping a ton here. We will see how the next few days fair, but for now it’s absolutely awesome.
