    GLA is the best at CO2.

    I did not want to replace my previous regulator however it was malfunctioning on the regular causing me issues. It was a cheaper competitor and worked for a few months only. I bit the bullet and bought this. Instantly I could see it was leaps and bounds my current popular model. It made my old one look like something out of a cereal box. This was easily twice as large and the overall weight and finish you just new it was going to be nice. Im now 8 months in and I have yet to change my cylinder. My bubble count has remained steady. I do recomend using mineral oil in the bubble counter. This way you dont have to refill with water all the time. Now I never refill anything! I love this GLA DS regulator!

    The very best of the best in co2.

    This is a very nicely well made regulator. I have a few competitor regulators but went with the OG's in co2. After seeing this regulator in person I knew I had to have it. Delivery was very fast, packing was phenomenal. Adjsting the bubble rate on a GLA regulator is super smooth, and linear. This equates to a more controllable flow vs some rate of chaos which I get from my others. This valve assembly is very well designed, with waterproof chord-grip and GLA's infamous manifold system. I like knowing I went with the original manifold company and my plants couldn't be happier.

    Way better then anything else.

    This is my last regulator. Ive used a few of GLA competitor regulators and I sent 2 of the 3 back for warranty and they never returned lol. The first two were DOA from Fzone and the 3rd was a co2fart regulator that kinda works so I keep it on my farm tank. However, my main display show tank gets the prized co2, my GLA DS. Dont be like me people, buy one time, not 4x. I thought I was saving money by going cheap and I did for a few months. But after a few months of constant adjusting bubble rates I decided to pony up a little more and go GLA. Huge difference, on everything. This is the pinnacle of co2 delivery right here.

    So glad I went with GLA!

    Buy with confidence because these guys are the real deal. Ive been shopping with GLA since 2007. Ive owned a few regulators from GLA and they all perform phenomenal.

    Way better than the rest.

    I can now say I own the best of the best. So done with my crap made stuff lasting me 6 months of epic hell. I feel calmness in my life now lol 5 stars!

    Way better than the rest!

    I sent GLA email after email because my co2art regulator has been nothing but headaches. Not only that the service was miserable with no results. Ive been using this GLA regulator for a few weeks and its unreal that I have not had to touch it once. I was literally fooling with my old regulator every morning before work. GLA made my life so much easier.

    Definitely the best of the best.

    No wonder everybody has been recommending me to go with GLA. I now see after owning one for 4 weeks. So much more stable and surprisingly much easier to set up, in terms of my co2 bubble rate.

    The best of the best in nature aquarium co2.

    Absolutely thrilled with my new regulator. Feels legit not all dinky like my dead one. Superb all!

    Finally a co2 regulator Im honored to own.

    Like many in the community I fell victim to the cheap co2 knock offs of GLA designed regulators. Even being cheap they were overpriced and would only last me about 1 year. Last February I purchased this regulator. I want everybody to know that GLA regulators are leaps and bounds anything on Amazon or the like. This is no toy, unlike the 3 others I have. The GLA regulator solenoid system and regulator body is 5x the quality and ease of precision tuning the others are. The needle valve has been untouched for a year, its rock steady. The feel,finish and just shear weight of these you can tell its full of quality through and through. Buy with confidence, go with GLA and dont be fooled like I was going cheap.

    Best of the best in co2 regulators.

    Look no further, dont waste your time with any other knock off of what GLA created. Anything less is a kids toy lol. Love GLA quality through and through.

    The best of the best in aquarium co2 regulators.

    I am in no way paid or sponsored by GLA so leaving this post is personal. Green Leaf Aquariums is the cats pajamas. You can find lesser expensive elsewhere like I did, but you will also pay the price in the end, like I did. I was totally blown away by GLA's dual stage co2 regulator line up. I chose this based on the ones I saw in my local fish store who was out of stock. Very well built design that actually has two large internal diaphragms. No toy parts like the ones on amazon. This is a real dual stage co2 regulator. I was honored to support GLA knowing they designed the modular manifold. They were able to help me map my co2 system for my 450g tank which was no easy task. It required extra manifolds in the end due to my tank requiring multi feed channels. GLA knows co2 systems, they are the real experts who install co2 systems for a living. Not just some seller selling co2 for cheap. These guys have mastered co2 delivery for aquascaping. Working with a company willing to help me along this epic journey is very admirable. If you need any help with your co2 installation, nobody is going to know co2 better than GLA. This regulator is quality through and through. Water tight chord grip, LED signal when powered on, super smooth operation of the needle valve making bubble rate adjustment a breeze vs chaos. Its everything a co2 regulator should be.

    I will be buying another system no doubt.

    I have all confidence this is the best co2 system I have ever owned. My wife is royally pissed because it seems Im buying a new co2 system every year. Its been a solid 8 months now and I can say this is the only system I actually find to do what it says. I like it so much I clean the crap out of it every month to keep it gleaming, its just so nice not not deal with the cheap brands any more.

    The only way to go is GLA

    GLA is the only way to go for co2 systems. Top quality and service you can count on. I received a free order of substrate fertilizer with this:) I was so happy.

    Outstanding co2 regulator and support.

    Quick communication, available via text everyday and the regulator is just super. Very nice finish and love the valve works. Hopefully my wife will let me buy another one:)

    A real profesional grade co2 regulator.

    This new GLA regulator has been extremely nice to work with. Save yourself the headache and go with the pro's at GLA. Nobody holds a candle to GLA co2 systems. You cant argue that when you actually get to see one in your mitts.

    So much nicer than my dead regulator. Fast shipping, couldn't be happier.

    The best of the best.

    This is going to be the most sincere review Ive ever left. I was approached by one of GLA's competing brands to accept a regulator for a positive review. My gut instinct was to take the regulator and run. Its a popular brand competitor but something felt off. I talked to a fellow hobbyist who was approached by the same vendor. I had already known the regulator they were trying to bait me with. It worked ok, not great but ok. It was real dinky and toyish like. It was super tiny. My stapler is much heavier and larger. Nonetheless I declined the offer. Instead I went and purchased a GLA regulator which I had plans to do anyways. Having already had experience using the competing brand, that is a total rebrand of all the rest I had good knowledge of the two. First, the GLA regulator is 3-4 times larger than the competitors. It uses real dual diaphragm design. The finish and valve assembly is much nicer in several ways. The bolt system is far superior as is the flow ration of the needle valve. Its super easy to adjust your bubble rate. The oring sealing system much nicer, and simpler in design. As it should be, GLA invented this modular manifold design. GLA co2 regulators are worth every penny. Assembled and packaged in the US. The support has been phenomenal. This co2 systems matches my new GLA Infinite 10-L filter like a champ!

    Top shelf co2 regulator.

    Replaced my shitbox Amazon regulator that everybody said to buy. Word of warning people, if its cheap its for good reason. GLA was super supportive and getting me pointed in the right direction. This regulator is the nicest piece of equipment under my aquqscape. The tune-ability of the needle valve is buttery smooth and effortless. The waterproof chord-grip is nice in that I dont have to worry about moisture inside the solenoid. The LED feature is really nice and will signal when powered on or off. I use mine with a ph controller so its on/off all day and its always on the money. Its truly a top level co2 regulator that certainly blows away the Amazon and cheaper guys. Heck the thing is 3x the size and girth! Think about what your regulator is missing and ask yourself, why is my regulator so tiny and toy like? Answer: Email GLA and they will be happy to outline everything. A++ service and stellar regulator.

    Outstanding co2 regulator

    Loving the quality and finish of the DS regulator. Its definitely more robust than my amazon regulator. I wanted to replace it with something more reliable and this time will not be a pain in the ass to deal with international help from China. I had one question in regards to the extras they sent and had a response in minutes. My aquarium is pearling with exceptional growth. Next I need to look into PPS-Pro dosing.

    The best from the originals!

    GLA needs no praise lol. It took no thought, I went with the best and the original co2 pro's. My 120cm aquascape is loving it guys!
