Perfect Paintball regulator
I ordered 4 of these regulators, for 4 different aquariums. Since I had limited storage space the best solution for me was to use 24oz paintball cylinders and GLA GRO regulators. Everything fits perfectly! Any other kind of regulator would have been too tall. I've ordered many products from Green Leaf and they are all exceptional in quality, as is the communication and attention to detail!

Reliable and Well - Built
I had been searching for the sweet spot in terms of CO2 injection in my tank. I have tried a cup diffuser, which proved to be problematic given the length of the tank with the lily outflow I was using. Also gave a shot to different regulators that just didn't cut it. Enter Orlando and team who kindly walked me through the many nuances of a regulator. I took the plunge, picked this bad boy up, and was pleasantly surprised with the result and stability. Regulators are a primary key in your CO2 injected system, and you might save a few bucks elsewhere, but you just can't go wrong with a quality build from GLA. Couple that with the excellent support and Warranty, and you have yourself a winner. Spend the extra $$ and get it right the first time. Save yourself the headache of searching for different things that "might work" and get something that will not only work well but last!

A solid and reliable bit of hardware.
I have a 45-P aquarium that could benefit from injected CO2. After all the days of shopping and research I concluded that GLA had the most suited option for my planted setup in the form of the Gro Paintball Regulator. The unit came promptly in secure packaging and was very easy to put into use. Unlike standard tank regulators, the paintball regulator does not utilize the included nylon seal as the paintball tank already has a gasket. Very convenient. Speaking of convenience, the included bubble counter/check valve and the solenoid make this unit very convenient as a nearly all-in-one CO2 regulator kit. The only real “task” to get CO2 running in the tank is finding a local supplier. (Hint: buy your tanks from the local supplier for potential discounts on refills) Be sure to also get a CO2-purpose coil of tubing and either an in-tank or in-line diffuser. Oh, and their customer service is by far the best I have experienced in all my years of online purchases. Quick to reply and helpful always. Order with confidence.

Thank you!
What a breath of fresh air this paintball regulator has been. After having so many issues with other brands this regulator has been a dream. The main selling point for me was the fact that this model can be used on every type of cylinder the market has to offer. It fits paintball,CGA-320 and disposable types. I think GLA should put that in the item description. Had I not contacted them I would have never known this. It arrived just in time for my christmas party woot! Thanks a million GLA.

Worth more than 5 stars
Support team was absolutely brilliant. I emailed them because I was having difficulty with installation and to my surprise I got a reply within minutes. Because of my busy schedule, I sometimes emailed them at midnight. I was walked throughout patiently even replying to my email at 4 in the morning. After buying -and spending on different cheap products, I regret not discovering this sooner. It works way better than others.

Takes some time and experience to tune it, but works like a clock now
I got this about 1 year ago just when they launched it. At first the pressure would swing like crazy. I didn't notice and just kept tuning it. After I lost all my fish (about 20 of them) I contacted them on messenger and their support was A M A Z I N G. They guided me through the process of disassembling the needle valve, checking it and assembling it again. Since then I've kept it at around 37-38 psi of working pressure with about 2 bubbles per second and my paintball tanks are lasting about 3 months. Plants a doing really well.

The best!
I replaced this regulator out from a cheaper one I bought. My old regulator for the life of me would not stay in tune. This one has been a set it and forget it. I absolutely love this regulator. It’s the best hands down!! Thanks GLA

GLA GRO PAINTBALL REGULATOR
I've had it for a week now, and I've got to say I'm really happy with my choice. I was going to go with something much cheaper, convert a disposable setup into paintball tank usage... But after reading so many reviews, so many problems with all the cheaper i decided to just get one nice system that would be well built and work forever. I'm really glad i did. The needle valve makes precise changes to bubble rate. (I set my working pressure below what was recommended to exert finer control.). I'm really happy. My planted tank immediately took off, algae slowed down.

GLA Pro Paintball Regulator
GLA regulators have been my go to since I began the hobby many years ago. I have never once had a problem with any of my equipment and the customer support from Orlando goes above and beyond what you could expect shopping anywhere else.

GLA GRO Paintball Regulator
This is without a doubt one of the best aquarium purchases I've ever made. The build quality is incomparable. Although shipping was slow (free shipping though) it was packaged in a way that it would be impossible to take damage during shipping. The needle valve is very smooth and easy to dial in to your exact need. No guess work or inconsistencies in bubble count. As soon as my timer goes on it is operating at the bps I set it to. This is not a product where shortcuts were taken. Again, this is an incredibly well built product with the consistency to match. Worth every penny
