The best co2 regulator!

If you landed on this page your here because GLA produces the best co2 equipment in the hobby. This is my second regulator I have had to purchase due to my previous model failing causing a mass die off of my fish. My local fish club recommended GLA as most the members also use GLA co2 systems. Now I see why, its super nice and very easy to use. The warranty is the best I have ever seen but I suspect I will have no issue with this fine piece of equipment. I can honestly say its the nicest piece of equipment incorporated into my whole aquarium arsenal. Fantastic price,tremendous build quality and unmatched service in the USA.

Best one Ive ever used.

This is an outstanding co2 regulator. Installation was very easy and I didnt need any help from my husband lol. This regulator may be more expensive than others but its clearly easy to see when your holding it in your hands and actually get to work with it. One thing I liked right away was that it includes a green LED diode that signals when power is on or off. Adjusting the co2 bubble rate was effortless and has been incredibly steady since I set it up a month ago. Top grade professional equipment you can purchase right here in the USA!. Cant beat this co2 regulator, I love it!
