Worth the investment.
Im loving my Gro system. Very nice quality throughout and have not had to make any adjustments since my drop checker turned green. Although I feel that every co2 system should come with a drop checker, this does not so make sure you get one. I purchased this one and could not be happier. https://greenleafaquariums.com/products/glass-orb-co2-drop-checker-kit-for-nature-aquarium.html

GLA Gro Aquarium CO2 System
I'm very happy with the system. Solid parts and put together extremely well. I will be buying another system. This is definitely a step-up from Fzone junk.
-
Worth every penny!
Honestly I'm surpised it doesn't cost more. The whole system is very high quality for what you are paying. GLA builds one smooth co2 system that Im using on my 150g tank. I added one of the inline diffusers and have been set and forget ever since.
-
Proud to own my GLA co2 system finally!
It’s been a wonderful experience getting my first co2 system up and running. GLA customer service was extremely beneficial to my tanks success. Beautifully crafted co2 system they put together and installation was super easy, even for being my first time! I was very proud of myself and I show it off to all my guest who can’t even believe I have something like this in my living room. The system works perfectly. Absolutely zero complaints. I just wish other companies had service like GLA. You won’t get a level of service like you get from GLA anywhere else. Great products!

Perfect co2 kit.
This system is perfect for my 50g in my apartment. I wanted a compact regulator and this was perfect. Heavy duty build quality and it’s been very precise with delivery. I absolutely love it!

GLA was super helpful and shipped this system to us for our aquascape and its been awesome. Plants and fish all happy 8 months in so far. Its amazing what co2 has done for our tank, the plants just grow overnight!

These guys are amazing and make great co2 systems.
Ive never been more satisfied with this level of customer service. The system was neatly packaged and installed very smoothly. The tank is finally busting with growth. coming from DIY co2 this thing is amazing, 7 months strong so far.
-
ONce slick well made co2 system.
Had tons of help from GLA and this system fit the bill. Received it and was very surprised, packaged with care and delivered with speed. More so was the ease of installation and quality of execution upon setup. Definitely highly recommend.
-
Best deal of a co2 system you will find.
I looked everywhere and so glad I chose this system. Everything was super nice. Thanks GLA.

Super nice and great price.
Loving the Gro system! Everything came packed like gifts, upon opening was top quality equipment I was impressed by everything including the sticker they provided. Installing took me all of maybe 5 minutes and I took my time. They even provide tools for installation. Everything was super smooth sailing from there. It’s still on the first fill only a few months but it’s been rock steady. I do refill the bubble counter when it’s empty which has me thinking of upgrading to there instant fill type bubble counter that requires no opening. Otherwise great buy with customer support like no other experience I’ve had.
