Most people skimp on the regulator....and it's gotten their aquarium in trouble. This GLA regulator is built like a freaking tank and it's quality is freaking amazing. Other people using GLA equipment either bought it because they wanted a quality product that would not fail or were forced to buy it because their existing regulator wrecked their aquarium.

If you buy this, it's money well spent if you take this hobby seriously.

Awesome co2 regulator.

Everybody already knows GLA makes the best co2 regulators on the market. Im here to share my experience with this GLA dual stage co2 regulator. I love everything about it. Great packaging,excellent build quality and easy installation. What I find amazing is how easy it is to get co2 set up, took me about 10 minutes and that includes opening the box. Ive had this regulator for almost 3 months now and have not had to touch it. I do clean it thought, it looks so damn cool! Thanks GLA.
