Sweet system from GLA.
This was way more than I had bargained for. Very nice complete system. GLA is a stand up company and you can tell in the delivery experience alone. The regulator is beautifully made and very easy installation, 2-3 minutes? Very high quality I have no doubt will last a lifetime, I love it!

GLA co2 systems unquestionably the way to go.
Long time customer of GLA and own a variety of co2 systems. I’ve had this kit 11 months now and it’s been terrific, absolutely problem free. I personally just started using mine without the bubble counter. It’s cool needle valve is designed to also accept a direct tubing attachment. My bubble rate is far to high to use a bubble counter so this really appealed to me. This system will outlast my lifetime and my family’s for that matter.

Huge upgrade!
Such a blessing, replacing my old system of several years and things have been growing really well. I dont have to fool with it any. I plugged ours into our bluetooth timer system and I can control the co2 with my phone! How cool is that?!

GLA is the best
We are absolutely thrilled with this system. Our 150g garden tanks plants have doubled in size. We decided to add GLA PPS-Pro fertilizers as well and growth has been tremendous. GLA is an American company thats been an extreme pleasure to work with and learn from.

Lovely co2 system for the price.
We shopped around for a while wanting something affordable and with quality to back it. This kept coming back as our one to buy every time we looked elsewhere. GLA has a wealth of co2 knowledge going back almost 20 years. They helped us choose this system and also helped us install it when we had general questions. We were intimidated by the whole process but GLA assured us its a walk in the park. And it was. They made it painless and my tank could not be happier. My kids love it! Now Im the cool mom on the block lol.

Superb co2 system but you need a co2 diffuser!
Absolutely pleased with this GLA co2 system. We were on a budget and this checked all the boxes. It arrived quickly as we were eagerly waiting, only 2 days! The packaging was very high quality and packed with care. Our first impressions were how nice everything was for the cost. It just seams in todays world at this price you expect much less, we got so much instead. It only took my husband about 9 minutes to get installed and running. He said it was effortless because the instructions are very very clear. You guys deserve more stars, so happy we found GLA.
