GLA PRO-1 CO2 Regulator
A step way above my last regulator, high quality and worth the price in my opinion. Great customer service.
best of the best
it is very good
The only UL Listed aquarium regulator on the planet.
We looked far and wide to find a good source for regulators for our laboratory. Finding GLA was a blessing because out other alternative was going to cost us 10x more. We test equipment that builds large incubators to grow green algae with the end result beings biofuel production. We now have 8 of these Pro series regulator in use and could not be more happy. The guys at GLA are top rate. Quality is unmatched, that goes without saying being UL listed equipment.
Quality through and through.
GLA has countless co2 systems throughout our facilities. We have been using GLA co2 systems all over the park and we could not be happier. We have been using GLA co2 systems for years, all backed by the tremendous team at GLA. Thank you guys!
Quality regulator and very heavy duty
I have real working knowledge of CO2 and regulators, I went with GLA because those who owned GLA regulators swore by them and really love them. They are certainly quality regulators. If you have owned any generic brand before, forget what you know about quality co2 systems because GLA has set the bar. This was easy to see since they invented the modular manifold years ago, now china is producing knock offs. I did look at co2art, but if you pay attention you will notice something. They mention in co2art the regulator is made in Germany, its 100% made in China. How do we know this? Because you now see the same regulator rebranded under many other names sold out of China. Shame on Co2art for lying to customers about where their product is made... Congrats GLA for staying the source and building US made products.
Best Regulator I’ve Used
This regulator is amazing. Sturdy. Made of brass (and not chrome). Dials in super-accurately and stays there. I can’t recommend this enough. Invest in this to start with and avoid the headaches that come with other regulators.
The best of the best in co2 equipment
You likely landed on GLA for your co2 system because you heard they were the best. Thats what brought me to GLA. I purchased this Pro-1 in July of 2019. Its been perfect since day one. I have a few other regulators I can compare it with and GLA is in a class of there own. This Pro-1 is super super heavy duty in all aspects. It weighs about 4x as much as any other regulator I own, its also significantly larger so Im sure that has a lot to do with it. Solenoid and needle valve have been spot on and super smooth. You can totally tell this co2 regulator is 100% built in the USA. Its also UL approved. What is not to love about that?! Good luck trying to find another brand thats UL approved lol. GLA is the best of the best in Co2 equipment.
This regulator has never given me a single issue. I'm actually just here to buy another modular block because I'm setting up a new tank. Disclaimer: I've begun to have a growing love for mechanical things with no overlying software to introduce unreliability for no discernable reason. I've begun my decent into grumpy old man. I bought this thing here about 4 years ago ,got a filled 20 lb CO2 tank from the hydro store ,hooked it up to a 20 long, plugged it in and it's still running on the same cylinder ( the tank readout needle has barely moved) without a hiccup as I write this. It's nice to spend the extra money on a something and be more than completely satisfied with the purchase. To me this is a no brainier, high quality, made in the USA and between it's reliability and the fact that after dial in with nutrients, I don't even think about algae anymore , if you're on the fence get off of it.
Pro definitely describes this regulator
From packaging to instalation everything was full proof. The regulator was packaged in a box along with other items i ordered using form fitted foam. Nothing was damaged in transit do to this style of packing. They give you step by step instruction to install this regulator correctly that are easy to follow. I also got a couple of GLA tools with my order and the quality was outstanding. The real difference between GLA tools and Amazon tools are the quality and the comfort when using them. I will never spend money on an Amazon regulator again. Spending a little more on a quality regulator will save you money in the long run as i have had cheaper regulators fail time and time again.
A solid build !
Shipping was great, and most importantly the way it was packaged, was unbelievable. Totally bullet proof. Well wasn't expecting anything less from a reputable company like GLA. Been away from planted tanks for few years now, and finally I'm ready to do it again. I set it up last night, and honestly comparing it to the regulators that I've had before, there is no comparison. It's a very solid unit and very consistent. I defiantly will have an updated review in the next few months. Thank you GLA.
It's a nice quality regulator. I had to adjust the working pressure to 33 psi before fine tune started working. When I first tried less than 33 psi on accident - it wasn't working. GLA gave me badass scissors and tweezers with it - I'm in love with both the instrument and tools. Twizzers are much better that those I had in a dental office when I worked as a dentist for a while - very precise. I wish the hombre who was replying to my email would had his head in the right place - I asked for a chemical to bring my DI water back to normal - he told me he would add it to my order, but I never received the thing... And now, following the commandments given me by my Jewish grandma, it hurts my soul to think that I would have to make another order and pay 15 dollars for shipment just to get the can of that stuff... All-in-all the regulator was an excellent purchase - much better than some shoddy Chinese regulators. Buy the inline ceramic diffuser with it - to get the best result.
