Review on Aquarium CO2 Regulator with 12V DC Solenoid - Large Dual Gauge Display, Bubble Counter, Check Valve - Fits Standard US Tanks - Accurate and Easily Adjustable Flow Meter by Antonio Cameron

I have two of these. The first was bought in December 2020 and has already ended. A bubbling leak has developed where the pressure gauge connects to the CO2 cylinder. I've been so busy the past few weeks that I can't possibly tell you how long this problem has been going on. The second one still works, but I'll keep an eye on it. subjected to constant handling and movement, wear and tear is to be expected. But for the CO2 regulator, which lies protected inside the aquarium stand and is only touched a few times a year. Buy something else.
