I love this thing. The best part is it fits all cylinder types. You will need to order tubing, keep this in mind. I had it up in running in 5 minutes, its perfect.
I have tried all the brands and GLA is the best quality product
I had originally purchased a regulator on Amazon for my setup. While that one did work, it felt flimsy and I had to tighten the solenoid every time I switched out tanks. I just wanted something I had more confidence in in the long right. Confidence in your equipment is a big deal when you have so much money invested in a tank that relies on it. So I went with this one and could not be happier. It feel more durable and was easier to get the bubble count correct compared to my previous regulator. While I have only had this one in use for a couple weeks now, I have had no issues.
I run this regulator on a 90g tank and so far its been great. I like that it will work on every type of cylinder on the market. Should my tank plans change this regulator is super flexible. Although its not modular like the DS model it still uses the same guts. Thank you GLA.
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.
I got this for my calcium reactor and its all I could ask for. Compact,heavy duty and uses legit water tight chord grip.
No more headaches from nasty finicky needle valves. Moving to a high end needle valve is an amazing feeling. It just works.
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!

Cant think of anything i could possibly critique, the regular was delivered quickly, went together quickly and easily, and is keeping my co2 levels perfect for my plants
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.
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.
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.
