    Cool slick dual stage co2 regulator.

    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.

    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.

    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.

    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.

    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!

    Precise and very stylish.

    Its hard to imagine what this looks and feels like in real life. I can attest to its precise control of co2 to my aquascape and its general construction. I like thats its very nicely priced full sized dual stage. GLA is the only one using two real internal diaphragms. I can understand this functionality due to my background in marine biology. I dont think I will be using mine on other size cylinders but I do like knowing I have this option. A very flexible regulator with the original GLA Modular manifold.

    Really nice upgrade from the Gro

    It was either this or the Gro regulator and Im glad I went with this. Mostly because the solenoid is modular so it will be able to feed a few tanks and I can remove an existing system thats not modular. Its been totally awesome, no issues couldn't be happier unless it turned into an ATM machine hahaha!

    Superior co2 regulator build and great price.

    Way better than my stupid co2art regulator. That shit box gave me more headaches than my aquascape of algae. The service they had was terrible. Fast forward to today with my GLA Mini DS and I swear its a night a day difference. Everything from the regulator to service with GLA was outstanding.

    I love this co2 regulator.

    I wanted dual stage and affordability as well as modular capabilities. This was an amazing bargain. The GLA solenoid was very nice to use. Very well made, nice finish and build quality really stands out to me. Great regulator at a great price.

    Very happy with this purchase.

    I replaced my Amazon regulator with GLA Mini DS. Beautifully made, compact and everything was effortless. GLA makes high end products and they have helped me every step of the way with my aquascspe in general. Green Leaf Aquariums is top shelf product and team

    I like it a lot!

    Very cool regulator, it’s rock steady everyday and keeps up with my 300g tank with ease. Don’t let the term Mini fill you. It’s capable of working on any tank size.

    Awesome dual stage regulator.

    This thing is awesome, ultra compact and super smooth at adjusting settings. The GLA solenoid is the jam pony!

    High quality and works flawlessly.

    I really like it, compact and easy installation. I dont use the bubble counter on mine. I opted to have the tubing attach directly to the needle valve. It has a direct factory connection option ready to go so I was pumped on that. This lets me squeeze the 5lb cylinder under my tank and its been perfect.

    Very high quality co2 regulator

    Exceptional build quality. Much better than the caca I bought in Amazon.

    Great bargain for such nice quality.

    This regulator is an absolute bargain. Coming from my crappy fzone regulator this was a night and day difference. So much better precision and control of my bubble rate. Ive not had to fool around with it once and everyday my PTSD from Fzone keeps me busy because I feel I need to check it daily. Ive had this now 47 days and its been rock steady. Not a blip!

    Super nice co2 regulator

    Above my expectations.

    I was tight on my budget needing to replace my still new regulator but the company refused to warranty my regulator so I went to GLA. Very refreshing and this regulator was just a treat. Easy and simple and super nice to adjust the co2 flow, it was effortless.

    It’s just beautiful. The needle valve for adjusting the bubble rate is like no other I’ve used. Bye bye co2fart lol

    Its an absolute gem!

    I love everything about it. Its very compact,modern and dual stage. I can add manifolds at anytime if I should choose to do so. GLA is the way to go, I cant fathom using any other system.
