Absolutely love this co2 system.
Was my first co2 system and could not be more pleased. Fast shipping(free lol) and the system was of stellar quality through and through. Packing was beautifully done. Thank you GLA for making this so easy for us!

So nice I bought it twice
I’ve been running this same setup on my 50 gallon for a little over a year now. It has worked so effortlessly that when setting up my 20g tank, I decided to buy the same one again. Highly recommended.
-
I own 3 of these, and love all of them.
Always a pleasure with GLA.
-
A complete co2 system for any aquarium size.
Im on my 3rd Gro and all 3 of my tanks are various sizes. What I like the best is you can use this on any cylinder available. To me thats the best in flexibility. It feels very heavy duty and stays set where you set it. Smooth operation through and through.
-
Aquarium co2 system made easy.
I wanted a system that was compact and easy to install into my Waterbox aquarium system. I added an inline reactor and its been a complete upgrade for my plants. They are now growing as they should. I would give more stars if they were available.
-
Aquarium co2 system easy to install.
Being my first co2 system I was a little intimidated. I wanted something easy to install and this was precisely that. I was able to get up and going in about 10 minutes. Its only been a couple months but the plants are happy. I was not doing so well prior to this using diy co2. Excited to try GLA ferts out tomorrow.

Premium aquascaping supplies.
Just took delivery of my new Waterbox aquarium. We needed all the guts to go inside the tank and GLA pulled through with flying colors. They helped us every step of the way and did not mind our millions of questions. Our co2 system is up and running and feeding our beautiful aquarium plants.

Complete aquarium co2 system.
Pumped I ran into GLA online. Service was tremendous and the help was priceless. The system comes with everything you need except the diffuser. So be sure to pick one of appropriate size. I love how they have everything in one button, and all the extra parts you require for your specific needs. My needs were very specific because I wanted a system to work with my 60g rimless cube. The Gro Co2 system fit the bill perfectly. Setup was a breeze with the provided instructions and video. You cant quite ask for more, GLA has you covered. Happy customer for life.
