    Rock Solid

    Posted by Bradley ONeal on 20th May 2024

    Worth every cent. Rock solid regulator. After getting used to the initial pressure build up, I set the bubble count and haven't had to touch it since. That needle does not move unless you touch it. First regulator I've ever owned that I didn't have to fidget with on a constant basis. Amazing construction, this thing feels like quality when you hold it. I was hesitant to spend the money when I first looked at this regulator. But the modular system, quality control, and the needle valve absolutely won me over. There's a reason they can charge what they do. Simply the best. You have a life-long customer!

    Well made, good reliability.

    Posted by Marvin Penington on 27th Feb 2024

    Good working co2 regulator, its very precise and rock steady. I was very surprised how well its made for what you pay. I work in the oil and gas industry so Im familiar for repeatability and reliability. This unit offers both, and you will see upon its form and function. The video instructions were terrific, cant ask for more. Kudos GLA.

    Exceptional co2 regulator

    Posted by Charles Young on 19th Feb 2024

    Very pleased, and I must say very nice quality and ease of installation. The precision of the needle valve is uncanny, much nicer than others I’ve used.

    Finally… I got what I paid for.

    Posted by Jay Talbert on 31st Dec 2023

    I just have a couple of small tanks but growing plants has always been the draw for me. I have used everything out there in the market to inject CO2. DIY… small CO2 cartridges… paintball tanks with Fzone regulators. Why I spent so much money on all of that I don’t know. It’s all about the regulator. No… it’s all about the needle valve! GLA ‘s regulator is the first one I have owned that actually is adjustable… and it stays adjusted! No more fiddling every day to get things just right. I would have and should have saved a few hundred dollars if I had gotten this one first… but I thought the others were good enough and I could make them work. Some did… for a week or even a month… but soon enough I was back to shopping for another “cheap” way to add CO2 to my tanks. This IS the cheap way!

    Lovely co2 system

    Posted by Patrice Bishop on 24th Dec 2023

    Delighted with this purchase and support from GLA Aquariums. Very profesional and extremely knowledgeable. A US based comapny with high quality co2 equipment you can count on. This was very easy to install and the adjustments we could tell were very precise, very well made equipment.

    GLA DS-Mini Regulator

    Posted by Dennis on 7th Dec 2023

    I've just set up this regulator, so I can't yet comment on its reliability and stability. I like its compactness and it's heft is reassuring. The quality of the finish is excellent and the components appear to be 1st rate. The only negative comment I have regards the difficulty in adjusting pressure because control knob is smooth chrome and quite slick. Knurling would improve it. It also has very short range of range of movement between highest and lowest pressure, making it touchy for repeatability of the setting. As I gain more experience with the regulator, I’ll update if allowed.

    Primo Co2 regulator.

    Love this, dual stage, compact and modular GLA style. Only the best!

    GLA is without doubt the best in the co2 game.

    Posted by Rachel McAlester on 17th Oct 2023

    Officially a GLA fan for 8 months. Having made the mistake of buying the cheaper competitor, Ive learned my lesson once. There are a few key notes to mention about GLA. Customer support is like nothing Ive ever experienced. They answered all my questions 7 days a week, even on Sunday. The regulator is built twice that of any Amazon crap box, because thats what Fzone ended up being. A real shit box. Luckily I was able to return it and get my money back and give it to GLA. The regulator is simply built larger and more substantial. It doesnt feel like a paper clip like the Fzone. Fzone seemed disposable lol. Whereas GLA you can feel the quality in your hands, especially the way the needle valve responds ot adjustments, it was like smooth icing on my cakes.

    Superb co2 regulator from GLA, we love it.

    Posted by Anthony Solerno on 31st Aug 2023

    This is one cool co2 regulator. Its dual stage, adaptable to all cylinder types. Its extremely well built and the needle valve is so much nicer than my previous needle valve. Im not very savy with the regulator tech, but I know when something feels well made, and this is no exception. The fines of everything and its compact build looks so cool in my cabinet. GLA when will you guys allow us to post photo?!

    Just perfect!

    Posted by Anderson Obregon on 27th Jul 2023

    After struggling with regulators from other brands I finally decided to go with GLA. Don't give it another thought. GLA products are made with lots of pride. The quality of the product is very evident. Better in every way than all the other similar products on the market.

    Beautiful design by GLA.

    Posted by Kevin Larson on 4th Jul 2023

    This is exactlyt what I needed. Compact and feature rich. Dual stage construction and GLA's sought after modular manifold system. Im honored to finally own one and it works phenomenally.

    Love all my GLA regulators.

    Posted by Dave Forester on 18th Feb 2023

    This is the only GLA regulator system I did not have, and yes I have all of them. I was shocked how compact this dual stage was. I had GLA add 4 manifolds to this and its an absolute machine. The action/feedback from this needle valve is superb. You can remove the bubble counter on these and connect tubing directly. This gave me an advantage to fit it in a tight space. All we needed was 18" for the 5lb cylinder.

    Very satisfied with GLA

    Posted by Alicia McDaniels on 11th Feb 2023

    We could not be happier, especially for the price. You get quality all the way and GLA has been terrific to work with for our needs. Today I came to buy a second regulator for our new basement system going in and is why I felt it necessary to leave a review. Thank you Marco at GLA for all your help and the lady on text support for helping me fix my GLA account lol.

    A great regulator as expected

    Posted by Lindsay on 22nd Nov 2022

    A great regulator. Came with everything I needed. No hassle set up, and the bubble counter is easy to adjust and holds steady. Absolutely recommend!

    Cool slick dual stage co2 regulator.

    Posted by Jamie S. Norton on 24th Sep 2022

    This thing is much cooler at home than in this picture. Its larger than it appears but still nice and compact. I have an ADA system but do not care much for the co2 hardware from ADA, so I went with the next best option. I love the modular ability and have not needed a 2nd manifold but Im sure I will soon now that I know I don't need multiple co2 systems. GLA pioneered this design so I figured why not go with the OG's of co2. Thanks GLA for such great products.

    Very high quality co2 regulator.

    Posted by Jeffrey Newsome on 7th Sep 2022

    For what I paid I was amazed at what arrived. A very well designed and thought through regulator. Its very compact so it has a very minimalistic look under my tank. I went full GLA for my engine room. I dont think I will be adding manifolds in the future but I like having the option. Its water resistant, very precise, I dont ever touch it besides refilling my bubble counter. GLA customer service is second to none. They have many ways of contact and i find the text service just incredible. You dont see any other shops doing tailored service like this. Its been a pleasure working with GLA since I started in 2008. Great people and 100% family owned folks. Cant go wrong with GLA.

    Very high quality and equal in stability.

    Posted by Asan Rashid on 4th Sep 2022

    Very pleased thus far with this regulator. Very stable and very nice looking might I add. In a few months I will be adding an additional manifold.

    This thing is cool.

    Posted by Martin Sullivan on 1st Sep 2022

    Really good deal for what your getting. Dual stage co2,modular manifold to expand to more tanks,fits every cylinder in North America. Thats why I chose this and glad I did. Its only been a few months but I literally set it up and have not even had to touch it. And it just looks so cool.

    Big action from a small regulator.

    Posted by Bruce Powers on 24th Aug 2022

    This regulator is just amazing in several ways. Super compact, dual stage technology,expandable manifold, GLA supported. What more can you ask for? You get a lot of regulator for your money. Great buy GLA!
