    My second GLA co2 regulator I love!

    Posted by Brandon Smith on 12th Feb 2020

    This is my second GLA co2 regulator. I ordered the standard DS series for an aquarium in my basement. The DS-1 series is going on my tank rack that I plan to have several tanks on. All I can say is the solenoid is of a quality you will not find anywhere else. Its clearly made of very high quality materials. Love the ability to be able to expand to more tanks with ease in the future. So happy to finally own the original manifold regulator.

    You will not find a better co2 regulator anywhere.

    Posted by Damon LeBlanc on 3rd Feb 2020

    I ordered this in December and what Im about to tell you is absolute fact. This is the best co2 regulator you can possibly buy. The modular solenoid valve is made to last you forever. The needle valve, well, its incredibly smooth and a breeze to adjust your bubble rate. The build quality is unmatched to any other brand on the market. My old co2art regulator sits in a box as a dead paper weight. Same goes for my Milwaukee rig as well. This GLA co2 regulator is clearly made of the best materials and craftsmanship. I should know because I took the whole thing apart. As a machinist I can confirm this is made with absolute precision using some really high quality machines. I purchased this after speaking with GLA for a few days because I was ranting my frustrations with my older units and sup par service. GLA service was fast and on point with what I was looking for. If your looking for a co2 regulator that will truly last you a lifetime need look no further, this is the one. Oh, the LED option on this is amazing! It lights up all 4 sides of the valve body and totally lights up my whole cabinet space in beautiful sunset orange color. Amazing build quality by GLA, they are the very best and designing and building co2 systems in America.

    Real profesional quality co2 system

    Posted by Samantha Reynolds on 23rd Jan 2020

    I love my new GLA co2 regulator. This has to be the very best co2 regulator on the market. My previous electronic co2 regulator is not even in the same class of precision,form and finish. This is a real true to life high quality piece of equipment. I can add extra manifolds at anytime if I need to feed more tanks. Thanks GLA for making such high quality co2 regulators from us plant geeks!:)

    SMOOTH, well done GLA

    Posted by Don Luthy on 13th Jan 2020

    I've owned 5 co2 systems in my life and only two were worth a !*&!, the first and the last. And GLA will be my last! My first system was basically a co2 bottle with a series of upside down cups submerged in the aquarium. Not the most effective system, but I did see some results and it was so simple nothing could go wrong. Thanks Tetra. Your system was exactly what you said it was. Although you failed to mention the bug you were bitting me with. Since then every system I've tried has been garbage. Leaking gauges, poor needle valves, regulators with two settings (full on or maybe tomorrow) I've seen it all. I had about given up. I found myself dreaming of those simpler days even if it meant having a stack of plastic cups in my aquarium. I don't know what internet rabbit hole led me to your web site, but there I was and I was trying every trick to talk myself out of buying another over-priced on/off switch for my 5 gallon Betta tank. Lol (I've got dreams, ok) Well, it arrived shortly after. 30 minutes after arrival it was running perfectly. Well, other than the leaky check valve i had left in line from my old system. BEGONE, DEMON! Thank you GLA, for providing me exactly what I have been expecting for the last 35 years. I would not change a thing. The looks are great, the Finnish on all the parts are perfect, every knob has the same smooth action, all the valves have perfect ratios for ease of use and responsiveness, love the bubble counter, and even great instructions. Most importantly though, one week in and I'm all ready getting great results. Will buy again. Will be trying more of your products. Gotta go plan that dream tank, talk to you soon.

    Outstanding!

    Posted by Magen on 12th Jan 2020

    I debated on this model or the standard DS series for a month. Im glad I went with the DS-1 series so I could expand to more tanks. However the biggest thing I noticed with this regulator is you can tell GLA cares about what they do. I purchased last year a co2art regulator that didn't last 8 months. I wish GLA allowed you to post pictures so I could show you how poorly made the co2art regulator was. Not only did the co2art regulator fail but the pressure gauge had a clearly obvious massive crack in the gauge. It was clear as day but I did not notice only because I had no idea what to expect. I tried working with co2art for repair but I learned they are in Germany, not in the US like the site they claim ownership of being located in the US. They are not! I ceased communication with co2fart and went directly to GLA for my co2 system. People, its a night and day difference. While the GLA model may be a little more investment, its not much more. You also get a company located in the US. They are not scamming you with some bogus website either. My GLA DS regulator has been absolutely flawless since we set it up. My husband works in making medical metal body parts(bone replacement) for surgery and he noticed how high quality the GLA regulator was compared to the Co2art, more like co2fart. Moral of the story is you get what you pay for. GLA is absolutely the only way to go for my planted tank and aquascaping needs. I should have came sooner.

    Thank you GLA!

    Posted by Sarah Workman on 21st Dec 2019

    Not only is the customer service amazing but this regulator is a wonderful addition to my planted tank. Im entering a few contest next year and this will certainly help. Super easy to follow instructions and such nice quality I could not fathom using anything but GLA co2 systems. Thanks to Laura for also helping choose so wisely:)

    Absolutely an amazing co2 regulator

    Posted by Robert Marcy on 19th Dec 2019

    I dont usually leave reviews but felt this was necessary. This regulator is hand over fist better than any of my previous regulators. I even own their competitor regulator and honestly GLA makes everything else seem like a tin can. Once you hold this regulator in your hand you will know right away its quality. The solenoid is like nothing you will ever see in the aquarium industry. Its an amazingly precise needle valve, and the LED they offer is like nothing else I have ever seen. The LED lights up on all 4 sides of the valve body, not some dinky LED you would typically see. The LED was optional but Im glad I went with it. If your looking to invest in a co2 regulator I can honestly say dont waste your time looking anyplace else because you will not get nearly the quality or service GLA is offering. The solenoid is also water proof completely, whereas all the others are not, that to me was a huge step in the right direction. The power supply is a molded connector making it impossible for water to get inside. Its also worthy to note the entire valve assembly is US made, and you can totally tell. Its completely serviceable at home for yearly cleanings so I dont have to worry about sending it anywhere for service. I can take care of it at home which to me is a huge plus factor. I rated this 5 stars and would have rated it higher because the service and quality is second to no one.

    GLA / Second to none!!

    Posted by Friedrick Siegmann on 11th Mar 2019

    Bought this regulator in fall of 2017 for my calcium reactor. It's been solid as a rock and GLA's customer support has been second to none. This is the top end and as good as it gets!! Love the led chip too. Reef 2 Reef build link below https://www.reef2reef.com/threads/govols-red-sea-s-400.308824/page-40 Marco, Thanks for all your advice and support along the way!! Freddie
