    Beautifully made with excellent delivery co2 system

    Posted by Issa Napoli on 14th Nov 2021

    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.

    Posted by Ivor R. on 21st Sep 2021

    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.

    Posted by Emmet Young on 17th Sep 2021

    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.

    Posted by William Wallace on 8th Sep 2021

    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.

    Posted by Aida Hughes on 6th Sep 2021

    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.

    Posted by Benjamin Bielinski on 30th Aug 2021

    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.

    Posted by Warren Lewis on 29th Aug 2021

    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

    Posted by John Dunkerly on 15th Jul 2021

    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.

    Posted by Jeffrey Higgins on 1st Jul 2021

    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.

    High quality and realiable

    Posted by Emma on 26th Jun 2021

    I am currently running two tanks with this system and I am very pleased. My established tanks has improved a lot and my new nano tank is growing some awesome Montecarlo also from GLA. Works as intended and it is very high quality.

    Buy with confidence from GLA!

    Posted by Krista Burbank on 26th Jun 2021

    I was so happy to find GLA. They helped me choose the correct system to fit my needs and boy are my plants super happy. First, customer service was second to none. The delivery was absolutely exceptional. Beautiful packaging with super easy to follow instructions... I was shocked, I never installed a high pressure system before. Im so proud of myself lol. The quality of the system is everything I could wish for. Thank you GLA for making this whole process so enjoyable. Best, Krista

    The very best aquarium co2 system.

    Posted by Robert Manuel on 4th Jun 2021

    Previouse to my GLA system I was using competing brands thinking that saving a few dollars was the correct way, I was totally wrong. I wish I could post photos to this review so you can see the difference between a co2art regulator and a GLA regulator. Its a night and day difference. The design of the GLA is totally different, its much larger. I learned this is because GLA uses two large opposing internal diaphragms. This equates to an actual dual stage. Whereas the previous models did not incorporate this. This is why they are so cheap in design and cost. The functional aspect was of great relief. I was able to tune in my co2 bubble rate with ease. It stays put everyday and the only thing I do is top off my bubble counter water. Customer service has been tremendous. I actually have not required much help, but they did help with changing my tubing color. Working with a real US based company has been a real treat, thank you GLA.

    The best co2 system in the aquarium hobby.

    Posted by David Wheeler on 10th May 2021

    Keeping this short and sweet as Im not much for reviews but I feel GLA is worth the time. I contacted GLA to help with a unique installation where the client tank at 1,000g required stable reliable co2 delivery. After a few short emails to Robbie at GLA they had a map of exactly what I would need. Customer support was A+. Shipping as fast as anybody could expect. Packaging was outright amazing, they should give classes to the rest of the buffoons who dont know how to pack. Quality, the feeling alone will tell you rite away when you hold one of these in your hand. Its not a dinky aluminum can like toy like you see with the other makes. This is an absolute true dual stage, big long body with 2 real working internal diaphragms. Top quality on every level and out client is totally happy. That makes us happy, we will be using GLA co2 systems in all of our client installations. Thank you GLA-Team!

    Worth every penny.

    Posted by Jonathan Riley on 5th Mar 2021

    This is my 3rd regulator from GLA. Ive been a regular since they opened in 2006. I still use all the other models from the previous decade and they work like they did from the first day I installed them. GLA is a family owned company so you are working directly with the manufacturer. I love that they are located in the US and the service is speedy. Its been wonderful watching GLA bloom into something outstanding. You can not go wring with a GLA co2 system, they are the original when it comes to aquascaping vitals.

    The best co2 system Ive ever used.

    Posted by Seth J. on 6th Feb 2021

    Coming from a lab setting perspective I can say this co2 system is the best system you can find. I have several others from GLA competitors which I will not name, but they are in no way the same caliber as GLA. Ive been with GLA since I started aquascaping in 2006. GLA was just a baby lol. This new DS-1 Co2 system is truly superior in build quality. If your hesitant just email them and they will be happy to provide reference photos of the competitors. That alone will be enough to scare you away from anything else. I use GLA co2 systems oddly for more than just my aquascapes. I work for the US government in a lab setting where we use GLA co2 systems to calibrate co2 sensors. There is a reason why we use GLA which I will not go into detail. I can say that GLA co2 systems are like no other because working for the government we have strict protocols on materials used in our lab testing. Long story short, GLA is the cats pajamas.

    Turn Key co2 system with super service.

    Posted by Barbera Sellers on 1st Feb 2021

    Ive never owned a co2 system before so this is my first as I dont have any reference for any other. I can say that it definitely feels like the most well built piece of aquarium equipment I own. I was nervous about using co2 but the instructions made everything so simple. If I was able to install this in 10 minutes without a hiccup anybody can. Loved the fast shipping and superb packaging. The best part about the whole experience was GLA has actual full complete co2 systems like nobody else. These guys have been building co2 systems since 2006, why go anyplace else? From what I understand they invented the modular manifold block. All the more reason to go with GLA.

    Best co2 system experience hands down.

    Posted by Brian Anderson on 3rd Jan 2021

    This is my second attempt at a high tech tank after my previous aquascape was a failure due to poor planning. Well, needless to say Im planning correctly and have had my GLA DS co2 regulator for 4 months now and could not be happier. Im confident you will love this regulator as much as we do, it not only looks like a true working dual stage but it actually is the nicest piece of aquarium equipment I own. GLA was prompt and extremely helpful in helping me replace my previous mistake. You have a GLA customer for life. Thanks Laura for all the guidance!

    Sooo much better!

    Posted by Vallarie Stevens on 3rd Jan 2021

    I dont have much to compare this regulator to as its only my second one. What I can say is that the GLA DS-1 co2 regulator is leaps and bounds to what I previously had. This regulator is a true work of art.
