    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.

    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.

    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!

    Quality built co2 regulator .

    Sadly I was in a pinch and needed a regulator quickly. I went to Aquashella this year and it was amazing! Unfortunately I came home to a dead regulator. It wasn’t a GLA regulator instead it was a popular Amazon model. When the GLA regulator arrived it was a completely different regulator than my Amazon regulator. I swear it made it look like my old one came out of a cereal box. You can buy with confidence with GLA. I love it!

    The original nature aquarium co2 regulator!

    I purchased this based on recommendation and I’m so glad I did. I went cheap at first using Amazon and my fish were all floating in my tank. Not sure what happened it had been running for two weeks and boom, dead. I was hesitant to do it again but this regulator just screams and oozes quality. I can’t even say my Amazon regulator would make a great paper weight but it’s to dinky even for that. My husbands happy and he doesn’t even know what he’s looking at but he knows quality when he sees and touches things. The DS regulator was up and running in a few minutes flat. Steady as a rock.

    The best aquarium co2 regulator.

    I feel my review today is important for a few reasons. The first, I have a fish room with 41 tanks but not all are planted but a majority are. I personally own one of all the competitors brand regulators. Here’s what I’ve learned and I feel you should know. 1. GLA regulators are nothing like co2art or UN and the other Amazon brands. I only know this because I have all of them. All the UN,co2art and Amazon Chinese brands are exactly the same regulator just rebranded. I say this because it’s 100% fact as I stare and look at these. These Chinese brands are built very small, almost dinky like if that makes sense. They are cheap these brands, and it’s clear why. There is not much going on with these regulators. The main issue with these regulators is longevity. Im finding I’m replacing them one by one as something in these brands all gave the same failure points. Im not sure what inside them is failing but after about my 2nd to 3rd cylinder refill these regulators lock up and do register psi correctly. I suspect it has something to do with the tiny parts in these regulators so I finally reached out to GLA. Now, I understand what’s going on. If you hold these Amazon cheap style regulators in one hand and GLA in the other you notice immediately that GLA is 3x the weight and size. This is due to the internal build structure of the regulator. It uses actual “Dual diaphragm” design. The cheap stuff absolutely does not. From what the engineers pointed out these cheap regulators use a spring the size of a pen to balance first stage working pressure which is fixed. This worm hole leads to the adjustable stage of the regulator where you can adjust psi at that point. This is the breaking point of these toy like regulators. How can one expect this tiny spring system to last under 1,000psi of pressure. Answer, it’s not and that’s why those regulators are cheap. Do your homework, better yet reach out to GLA engineers and they will do better at explaining mechanical operation of these regulators. I’m done wasting my money and will only use GLA from now on. In short, lesson learned don’t by cheap because it’s cheap. You’ll regret it on something like your nature aquarium aquascape.

    Gla pro ds Co2 regulator

    I really like this regulator. It is very well made. Very easy to use. Gauge is also easy to read.

    Best nature aquarium co2 regulator.

    Great quality and superior craftsmanship backed by the creators at GLA. I took pleasure of meeting GLA and team in Florida this month. Seeing is believing, they showed me the worlds first prototype of the modular manifold they invented. So dont be fooled by what competitors say. GLA is the original and the regulator exudes that and then some. Easy to use needle valve, LED light for the solenoid and stay put adjustments. I never have to touch my needle valve. The set up guide and videos were perfect. Top quality through and through. Thank you GLA.

    Aquascaping supplies at its finest.

    Now my 3rd GLA regulator but this one for my basement so I could not branch off from my other regulator. Great bit of kit, well made and super stable flow rates. GLA is a trusted aquascaping supply shop who knows co2 better than any other vendor. You can email,text and chat with them with a click of your mouse. Im a GLA fan boy for life lol.

    Professional grade aquarium co2 regulator.

    Well designed and made. I like the ability to add modular manifold blocks without the need to buy another co2 system. I had my wife perform the install due to an injury. She passed with flying colors. The system is super smooth and perfectly set where you leave the settings. The big dual stage body makes my Amazon dual stage look like a kids toy. Go with GLA.

    Best aquarium co2 system.

    So glad to find GLA, they are my new go-to planted aquarium store. This regulator arrived timely and was much higher quality that anticipated by a mile. Service was top notch who also helped with some added details for my system.
