GLA GRO Aquarium CO2 System

For a co2 regulator being so compact it sure weighs a lot. Its a dense hunk of metal that goes on buttery smooth. It took me all of 5 minutes to get up and pumping. Adjusting co2 was super easy, Im amazed I was able to do this by myself. Thanks to the instructions and videos they provide its a piece of cake. The GLA co2 tubing was much nicer than anticipated and meshed perfect with the inline co2 reactor. My tank is loving this system!

Works perfect and easy to install! Thanks

This is only my second co2 system so Im not an expert. This kit was leaps and bounds from my co2art regulator, which was more of a lightweight paper weight that could barely even do that as a paper weight. This Gro system comes with an actual industrial grade co2 cylinder,tubing and inline check valve. The only thing you need to add is a co2 diffuser. I opted for GLA's 90mm Atomic diffuser and the pair are absolutely perfect. Its been about 9 months now and I could not be happier.

I really was not sure what to expect as this is my first co2 system. With no experience I was able to install this system in a matter of minutes. Everything was super easy to follow, they even have some youtube videos explaining things. Customer service was like no other experience Ive had online before. They answered questions at all hours even on a Sunday. What the heck more could you ask for? Thank you GLA for making this so easy.

I like the simple yet well-built product. I also appreciated GLAs customer support since I needed a few questions answered as I was setting this up.

Quality well built CO2 system.

This is my first experience with injected CO2 and I gotta say you cannot go wrong with the GRO system if you’re new to CO2 in aquariums. I got mine along with an in-line aluminium diffuser from GLA in September but I didn’t set it up until December when I finally got my hands on a tank the size I needed (thanks pandemic for messing up with supply chains! Sigh!). At times I was dreading the day of finally setting up my aquarium because it mean to put together this CO2 system, thinking it’d be nightmare of a precision work cuz we’re talking about pressurized gas. Far from it! The instructions that came in the package are super clear and fool-proof and I got my GRO system set up and running in less than an hour! Besides tinkering with the appropriate rate of injected CO2 for your tank, the GLA GRO CO2 system, when connected to a timer, is practically “set it and forget it!” (until you have to refill your CO2 cylinder, that is).

Fantastic regulator I could not be more thrilled with. Ive used many other brands of co2 regulators for my planted tank and reef tank, but GLA takes the cake when it comes to co2 systems.

This Gro system has exceeded my expectations by a mile. For a complete system with cylinder this kit is hard to beat. Its backed by GLA full customer support system which as a newbie I was totally grateful for. My 75g tank is a showpiece in my house and the topic of discussion every time we have guest. Its the GLA co2 system that really propels the discussion in my home when guest see it. It looks very sleek,clean and neat. Its perfect for the compact space I have under my 75g tank. I do love this regulator:)

This is one great aquarium co2 system. Everything from form to function of this system has been exactly what I wanted and is why I went with GLA. The only thing this system did not come with is a co2 diffuser, which I totally understand because there are a tone of sizes. GLA was there for me with helping me choose a co2 diffuser for the tank Im setting up. I opted for the co2 reactor they sell and it has been working flawless now for almost 2 months. You will notice the quality the minute you set this co2 system up. Super easy instructions and only a few minutes of install time. I spent the next few hours just marveling how nice it all was lol.

So happy with it!

I lost my first unit in a cross country move. I knew I would be dissapointed by a different replacement. The directions were easy to follow and all my connections were good the first time around also, the gas cylinder was cheaper than I could source it myself.
