    Cant wait for the new model to come out!

    Amazing dual stage regulator thats super compact and built elegantly. I emailed GLA to see when stock would be back and I was suprised ot hear they have a new revised version coming out with modular abilities. I will definitely be going this route when they are back. GLA is truly the only way to fly with co2 system. A+++

    GLA MINI-DS CO2 regulator

    When I received the package everything looked perfect. After install I noticed CO2 leak from regulator fitting and it wouldn't tighten onto CO2 tank . Found all fittings loose. I had to re-assemble the entire regulator. This was not my first regulator from GLA which came in perfect. QC issues on this one. Staff Reply: Thank you for your review. The fitting to the regulator is interchangeable. Its designed to be installed and removed with easy. This is why we supply you with the tools to install. No real amount of "assembly is required". Its as simply as tightening the main stem. Basically, one big bolt. Easy to do with our supplied tools in the box.

    Superb regulator.

    I love it, simple and has all the features of the best minus the HP gauge. Im buying a second one and I hear they have a model with modular manifold and thats the model I plan to get next.

    As good as it gets for mini dual stage co2 regulator.

    I absolutely love this dual stage regulator. Its heavy duty, compact and completes my full ADA system. I love that you can opt out of the solenoid. I run my kit without a solenoid using the slow drip method 24/7 and my aquqscapes never looked better. No electricity required. The build quality is top shelf. Way to go GLA!

    Amazing quality and simplicity

    I ordered this regulator without solenoid so I can have a slow drip of co2 24/7. I wanted simplicity because of the ADA glass cabinet I use and it meshed extremely well with the installation. This dual stage co2 regulator is like no other you will ever see. Clean,dual stage and installs in minutes. Luv luv luv.

    I love it

    This has to be the sexiest dual stage co2 regulator available. Its super heavy duty and the options you have during check out to have it built are really nice and its why I chose this model. For starters I use this with a full ADA system and this regulator simply ties it all together. I use this regulator without a solenoid and its been incredible. My co2 stays stable 24/7 without skipping a beat. No electricity required! The needle valve is just butter smooth and has a constant everyday reliable bubble count. The only thing I do to this co2 regulator is polish it from all the fingerprints my friends leave all over it from drooling al lover it. She's a beauty GLA!

    Love it

    Without a doubt the most compact dual stage you will ever see. This regulator was perfect for my 55g tank with limited stand height. I really like the fact that it fits every type of co2 cylinder but more importantly is the build quality. This is the nicest piece of aquarium equipment I have ever seen. Most of my stuff just feels like cheap plastic garbage lol. Not this regulator though!
