    I love this regulator.

    Posted by Jesse Daniels on 20th Mar 2021

    What a terrific regulator, exactly what my tank needed. It came with everything in the box you would need to install and get moving. Came with all the tools to install and even service it in the future. Installing it was super easy, only a fe w minutes as the instructions are super easy to follow. I also found this helpful,https://www.youtube.com/watch?v=K_Sv5Vb4yfg&t=53s You will be extremely happy with your Gro regulator, top notch.

    Quality matters

    No more headaches from nasty finicky needle valves. Moving to a high end needle valve is an amazing feeling. It just works.

    So far am very pleased

    Posted by Kat on 22nd Jul 2020

    I received my regulator 2 weeks ago and must say I am very pleased so far. My old regulator had a crap needle valve and would dump CO2 into my tank sometimes. After installing this regulator and also getting a new co2 diffuser (I got a metal one since I broke the glass one when taking it out for a cleaning), my plants are looking quite happy and there is a steady stream of bubbles into the tank daily that I haven't really had to adjust. I will say an improvement to the design could be painting arrows on the dials to indicate which direction to turn the valves in- not gonna lie that confused me very much upon installation. Also, there was one day where I set the pressure for 40 ppm? and the next morning it was at 20 ppm. However, that could have been other factors and not the regulator's fault. Anyway, overall so far I am very glad I spent the money on this regulator! Also, GLA's customer service was helpful. __________________________ Reply: It was a pleasure helping you with your co2 system. When setting up its critical to always adjust your PSI with the solenoid activated in the off position. This will keep any upstream pressure from effecting physical adjustment of the psi gauge. Its a basic mistake we see made often. However no harm no foul because it can not damage anything. It only takes basic procedure know how and the rest is breezy. Thank you for your trust and support! Best, Laura @ GLA-Team

    Beautifully made, sturdy, and functions immaculately

    Posted by Vic on 3rd May 2020

    One of the more well made pieces in my setup. Too bad it has to hide in the cabinet. This regulator feels sturdy, and the dials are well made and so smooth. Highly recommended.

    Excellent co2 regulator

    Posted by Ken Brill on 3rd Feb 2020

    I bought this regulator along side a GLA DS series co2 regulator. I use this one on a 10g tank that has a small cabinet space so I needed something compact. I was not totally sure what to expect when it arrived but I can say this co2 regulator has a really nice build quality. The needle valve was super easy to adjust, install was almost thoughtless. I had it installed in under 5 minutes. This co2 regulator was above and beyond my expectations. GLA service was second to none to boot.

    Perfect

    Posted by Judy Alvarez on 28th Jan 2020

    I dont know much about aquarium co2 systems, this was my first. Its been a couple months since I had it and its been absolutely great. The only thing I do is refill the bubble counter and wipe clean regularly with plant based metal cleaner. Its just so pretty I cant help but to keep it looking so good. Its the nicest piece of aquarium equipment I own and it was only $150. Very happy with all my purchases from GLA.

    Its awesome

    Posted by Christopher Buckaloo on 24th Jan 2020

    This regulator arrived very well packed in a nice fitted box. Upon opening I was greeted with super easy to follow instructions. Literally took me 3 minutes to set up this co2 regulator. Im using this in a 30g aquascape I plan to enter in IAPLC 2020. Everything about this regulator was so smooth and tight. From the adjustment knob to the needle valve everything was super smooth, thats the best way to describe it. Your going to love this co2 regulator no doubt about it. I give it 5 stars and an A++ GLA.

    Excellent quality co2 regulator

    Posted by Paul Savion on 22nd Jan 2020

    Ordered this no a Wednesday and arrived to me on Friday. Very well packed with super easy installation instructions. I use this on my 75g tank and so far everything has been A+ perfect. I echo what many have already said that the regulator is truly buttery smooth. Dialing in bubble rate with this needle valve is beyond easy, so much better than my previous co2 regulator. A+ product all around.

    Perfect A+

    Posted by Sam Garison on 29th Dec 2019

    I got this to add carbon to my 20g tank and its been about a month now. I really like the bubble counter being attached and the fact its able to swivel out of the way and be used without bubble counter. I opted for the complete system option because I needed a complete co2 system. GLA co2 system is absolutely worth every penny. Fantastic support and easy to follow directions.
