Customer Reviews

Super co2 system.
Super happy with my order. Very high quality and much better than co2art reglator. Im not sure why anybody likes that thing it was such expensive garbage. This kit though has one less pressure gauge and still out performs.
-

Big bargain for such a solid kit. Super pleased and came to buy another one with the new Gro manifold thats coming out(they sent me pics its rad!). The new Gro can feed 2 tanks at one time, pumped!

Superbly built system from GLA
I have some co2 systems from Amazon and one my dad gave me years ago but none of those were reliable from the start. I opted for GLA based on reputation and man this system is nice, the regulator is very well made and not some junk ass paper weight. Flow control is optimal and GLA nailed it, its perfect.

Installed it today, and is working like a charm

Nice quality and a bargain of a price when you compare.
I did a lot of looking around and even went to the local fish club meeting. Our club was surprisingly huge as it was my first time going, 198 people! Everybody spoke highly of GLA since they have been doing co for planted tanks since 2006. They were very helpful in getting me sorted out. My family aquarium looks so nice! It was easy to set up and its been a few months now. We have not had to touch it once. Thank you GLA!

We love this system from GLA.
We knew wwe wnated to go pressurized co2 for our new tank and after days of research we decided to go with GLA. We are so glad we did. Its exactly what America needs today. These folks have been at this a long time and they are tried and true for decades. From what I understand they invented a lot of what you see developed today. Impressed by the customer service we took the plunge and our tank could not be so lush without the help from the co2 system and GLA's guidance. And guys, they have this neat text service I made my wife use lol. What a treasure, GLA. Worth every penny and more.
