Description
GLA Modular CO2 Manifold Expansion Block
Expand the CO2 distribution capacity of your existing GLA regulator with the GLA Modular CO2 Manifold Expansion Block. Each precision-machined block adds an independently controlled CO2 outlet, allowing you to supply multiple aquariums from a single regulator.
Each manifold block includes a built-in precision needle valve and integrated bubble counter, providing fine control and easy monitoring of CO2 delivery to each aquarium. The modular design allows you to expand your system as needed by adding additional blocks.
GLA manifold blocks are designed specifically for use with GLA dual-stage DS and DS-Mini CO2 regulators and install quickly using our modular expansion system.
Choosing the Correct Version (G2 vs G3)
GLA regulators have been produced in multiple generations. When adding a manifold block to an existing regulator, it is important to select the correct version that matches your regulator’s needle valve design.
Important Compatibility Note: Generation 2 (G2) and Generation 3 (G3) manifold blocks are not cross-compatible and cannot be mixed. Please verify which generation your regulator uses before ordering. Refer to the comparison photo in the listing or contact our support team at info@greenleafaquariums.com for assistance.

GLA Modular Manifold Block
Matches the one that came with the regulator exactly. If it works the same as the original I will be a happy camper. Very smooth, very precise and stays exactly where you set it.

GLA MODULAR MANIFOLD BLOCK
Got this as an add-on for a 3rd planted tank. As with everything with the GLA name on it, it is excellent, and works flawlessly!!!!!!

These are phenomenal
GLA always had the highest quality metering valve. This valve is no exception, super precise and the curve rate is superior to the crap on everything else.

Love GLA manifold blocks!
I have 14 on my co2 regulator lol! Yes, it looks totally wild and I have the cylinder anchored. With that said these needle valves are amazing. Super smooth and the bubble rate is not all crazy, its smooth and easy to dial in. Thats why I now have 14 lol.
