Customer Reviews

Love the product, but don't need it. I've tried multiple times to contact customer service, with no response. All I want is an RA# to return the unopened, unused items.
I wish GLA would respond to my text and email requests.

GLA GRO AQUARIUM CO2 SYSTEM
Packaged very well and simple set up, once I had CO2 I was able to set it up very quickly! Love it.
-
Worth every cent and then some.
Im not novice to co2 systems as this would be my 3rd go at high tech. Ive used a systems in the past and using them was a pain in the ass. I was always fooling with the system to get my bubble count steady, almost daily. It got so bad I had quit the hobby for a few months. Back in a new house and fresh new aquascape, introduced the GLA Gro system and I was completely amazed how effortless and easy it was. Ive not touched the bubble count in months! This system is steady as a rock and extremely well made. GLA support is second to none.

Love GLA Co2 systems.
Our 2nd full system from GLA. Our first one is still going after 7 years on our Angel tank. This system from GLA is a testament to GLA quality. A full US made co2 cylinder with a superb co2 regulator.

Easy Set Up, but tank is older
This was really easy to set up for my first co2 system! The only issue I found was that the tank was almost a year old at the point I received it. The folks who filled it for me said it was manufactured 10/22 and I received it 8/23. Thankfully it's not expensive to get it hydro tested in four years!

GLA is my go to from now on!
Superb system, all you need is a diffuser. GLA was very helpful at getting my needs taken care of. Everything is of premium quality. Lots of US made parts and lots of good hands on with the foils at GLA. We could not be3 happier with the performance of this system.
