Great CO2 Regulator

I have tried other regulators in the past. Never had much luck with parts breaking, quality, and other issues. Decided to go with the GLA as I had heard from others that they were great quality and worth their price. I can honestly say I have not been happier and my planted tank is doing amazing. It is truly worth the extra money and is superior to any other companies’ regulators that I have tried. Will definitely be using them for future purchases. And the diffusers work amazing as well.

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:)
