    This is the best co2 regulator and service.

    On an emergency I needed replacing my old co2 system. My co2art regulator chekc valve failed and flooded the regulator. I tried to clean it and purge it of water with no luck. They had no service option either so basically became trash. Super important factor GLA should advertise, you can service and rebuild a GLA regulator! First impressions, very high quality, you can feel it and visually see it. The finish is much nicer than co2art and the precision of the bubble rate is much more linear. The solenoid is very well made and the bolt design is much nicer and much more compact and finished. It also has a water tight chord grip leading to the LED. I should have went GLA from the start.

    Only way to fly is GLA.

    I echo what many here say, GLAS is the way to go. Ive tried all the competing brands and GLA is leaps and bounds in quality and flow rates. The needle valve is sooooo much nicer. I love it!

    Very much a professional grade co2 system.

    I found GLA through with recommendation to go with GLA for our aquascape at home. We loved the system so much we ordered another for our office aquarium at work. GLA has been an absolute blessing to work with. Highly recommended them.

    The best of the best in aquarium co2 systems.

    If your reading this review you’ve landed in the right place for your co2 system. I had inquired with GLA due to an urgent need for a co2 system because my current one was struggling. I was having to monitor the co2 daily and make constant adjustments. That’s only after 3 months and do use on a brand new regulator from Amazon. Needless to say, this system is exactly what your looking for in a complete co2?system. The team at GLA assembles,test and package your co2 system in house. This in itself is quite amazing with technical products like this. They provided very clear instructions along with top shelf packaging. You can really tell GLA has there stuff together and they love co2 systems. All the tools were inside the box along with links to videos to get going. I had plenty of experience fooling with my previous model so installing this system took me only 3 minutes. Everything was just so smooth, adjusting my bubble flow rate was effortless. The sad part, my ptsd from having to constantly fool with my last co2 system, I kept going back to check it. It was rock steady say in and day out. Thank you to everybody at GLA who saved my aquascape from disaster. By and far the best customer experience of my life. I’m a fan forever.

    Go with GLA, dont be like me.

    My first co2 system from co2art was total garbage. Wife is extra pissed I wasted that coin on them. Had I known about GLA prior I would have totally went with GLA. My god, the difference is night and day. People, dont be fooled because that other shit is absolute garbage in comparison. I reached out to GLA for a few basic questions, they responded quickly and were very helpful. This system is the way to go 100%. Dont be a sucker go with GLA!

    Best co2 system available.

    I spent days doing my homework, at one point considered building my own. After much research GLA was the way to go. Im glad I did because its been excellent. I was not endorsed or paid to leave this review. I only wish I could attach photos of my aquascapes to this review. Save yourself the headache and go with GLA.

    Go with GLA!

    My wife was super upset that I needed to replace my co2 regulator for the 3rd time. I never could afford GLA systems and always bought the low dollar equipment. Im not evcen sure why all that cheap stuff has such great reviews. They are all toy garbage. When the GLA regulator arrived I knew instantly I should have bought this years ago. Dont be a dummy and save your money. Buy GLA co2 systems. Everything else is just generic garbage.

    The best complete co2 system on the market no doubt.

    Very happy to leave this review for GLA. This is my 3rd complete co2 system thats actually complete. While it doe snot come with a diffuser it has everything else. No system should come with a diffuser. Thats like giving away free shoes in a one size fits all solution. The GLA co2 system in terms of quality and ease of use gets an A+. Complete with instructions and how to videos. Many components are made in the USA and the co2 system is assembled and packaged on US soil. No other company is offering this level of service, and is why you should choose GLA.

    Beautifully made with excellent delivery co2 system

    I buy now my 3rd co2 system for my aquascapes. GLA co2 system is above and beyond what I currently have. Beautiful finish, large regulator body and easy to adjust co2 flow rate. The manual provided was easily followed and no hiccups at all. Thank you GLA

    Profesional co2 system.

    GLA was very helpful in getting me exactly what I was looking for. I leave on business regularly and needed a reliable co2 system. My latest business trip was the last draw for my cheap Chinese co2 system. Upon return was an absolute nightmare. Dead fish and algae were everywhere. I reached out to GLA for help and what I received was more than I could ask. I shop a lot online, like everybody else. Working with GLA was much different. You can tell when you receive your shipment before even opening it that these guys care more about what you receive than anybody else. Everything was packed meticulously and the performance of the co2 system was luxurious. I had to restart my tank completely after my disaster, but Im confident I can rest well when Im away on business. This system is 100% precision made co2 system. From the tubing,check valve and cylinder all the way to the tape on the box. Im a fan for life, so glad I found you guys :)

    The best all in one co2 system for aquascaping.

    I looked at every available option and GLA always stood above the rest on every aspect. Quality built co2 system assembled in the US. The regulator and cylinder are phenomenal. The one thing these co2 systems do not come with is a co2 diffuser, but for good reason. Providing me with a basic general diffuser would not suffice because diffusers are not a one size fits all solution. Knowing that I went with a reactor for inline use and I purchased the new stainless steel canister filter GLA has and my cabinet space looks amazing. So amazing I removed the doors. Save yourself the headache and go with GLA. I pestered them with a million emails and they gladly explained everything and going as far as providing a quick Bio about GLA. They are the original goto co2 gurus. Having invented the modular manifold you have no reason to look at knock offs, because thats what the rest will be. They have terrific pricing and top notch customer support.

    The best aquarium co2 systems.

    Like everybody else I shopped for days. After consulting GLA to ask them a few questions I was absolutely sure I was going with GLA. Setting up the system took me about 15 minutes because I move a little slow. Everything was absolute precision. My diffuser was blasting out co2 rock solidly now for 4 months. My tank is glowing with colorful growth and is why Im here today. To buy another co2 system, we cant wait!

    GLA has the best aquascaping supplies.

    I took a long time in deciding my next co2 system. My husband was not happy with my previous budget purchased co2 system so he was very hesitant. Green leaf Aquariums eased his pain with flying colors. This system that was delivered was a professionally assembled and packed co2 system. Everything was beautiful. My husband commented right away, "Ok, this is next level sh*t". I totally agree, the GLA co2 system you can immediately tell it was built by a reputable team. The procedure for installation was easy especially with the provided instructions and videos. You have a customer for life. Thank you from the Hughes family!

    Undoubtedly the best aquarium co2 system.

    By far the best experience I have had purchasing and using a co2 system for my planted aquarium. Packaging was top notch. I really like the quality of everything especially when comparing it to my previous system. Super high class kit all around.

    Aquacsapings best co2 system.

    I have had this system now for about 7 months. Its been flawless since day one. If your looking for a co2 system from a company who designed and built the modular manifold, look no further. Nobody else can claim this prize but GLA. You get expert tech support from the actual designers of the modular manifold system. You have a support system just a click away at your finger tips. They are located in north Florida and not overseas. You will be hard-pressed to find a company like GLA who does the work and support like they do. I used the instructions that came with the system to install the kit but you can also look at the links they provide. In all its quite simple. Even my wife loves the co2 system and has no idea whats going on lol. The quality of the build is superb. I would advise on keeping it clean in orderfor it to stay so damn pretty. I wish the rest of my equipment looked this nice. I know I will be one of the first to buy the new canister filter they are coming out with. Facts!

    GLA Pro-DS-1 Dual Stage CO2 System

    I had a paintball tank with an “Amazon special” regulator. Switched to this system and all I can say is…”Why in the world did I wait so long?! I was reluctant a bit because of the price but I figured if the quality is there then I can accept a higher price. THE QUALITY IS THERE! I purchased the regulator, tubing (very nice that came with it), check valve, 5 lb tank, 70mm Atomic Diffuser with built in check valve, brass Permaseal (which I can’t recommend enough) and they threw in the GLA Substrate Fertilizer Caps. Zero issues hooking everything up and getting regulated. If you’re on the fence…get off! This is the REAL DEAL!

    The best co2 system on the market.

    Seriously, your not going to find a better more high quality co2 system anywhere. You get what you pay for and Green Leaf Aquariums co2 systems are by far the pinnacle in the industry. This is my 4th system after my previose kits from Amazon all failed with tragic endings for my fish. With Green Leaf Aquariums co2 systems you are getting the absolute best in the industry. They have decades of service providing co2 systems so why bother buying cheap when you get US based customer service right at your finger tips. I love the way the co2 system came packed, and the bonus stickers! Quality outshines all my other trash and I even kept the packaging, not even sure why lol.
