Review on Pressure Regulator Magnetic Aquarium Equip by Yvette Gonzalez

When I first got this regulator it worked fine. It did what it had to do - set it up right at a reasonable price. When it was about to empty the tank I kept a close eye on it as it was a one stage regulator and there was so much talk about potentially releasing too much CO2 into the tank which could harm the fish. It never happened. Two-stage regulators are more expensive, so a working single-stage regulator will do. Why 2 stars? This regulator struggled every time I had to fill the tank. There was some difficulty in properly attaching the regulator and preventing leaks. I even brought the regulator to the shop where I put in CO2 and they didn't know why it kept leaking. He had the right puck. Bought to replace this other controller.
