The best co2 regulator I have ever come to know.
This is my 3rd go with co2 systems for my 180g tank. I tried using a couple other brands that are well known but I should have took warning from my local aquarium club. I started with a co2fart regulator, then I thought I graduated to aquariumplants model. After wasting time and money with these I took 5 months off and decided to try again. This time I went GLA and my god has this been a breath of fresh air. First off, the build quality is night and day. I shit you not those other models were no joke toys, or likely just not made well for long term use. You get what you pay for and myself including my wife are very happy with GLA. Topshelf service and quality all from a US based company you can count on. My tank totally thanks you GLA:)
