Review on 🐠 FZONE Aquarium CO2 Regulator with Dual Gauge Display, Bubble Counter, Check Valve and DC Solenoid for Plant Grow DIY CO2 System CGA320 Side Open Cylinder by Carolina Tavarez

Works as expected. Great price for what you get! Please, please use tape, not just a little bit. Use a good amount. The better you protect the male threads when screwing everything together, the more likely it will work, NO leakage or very little leakage! Tip: all with an external thread, use adhesive tape! Regulator pin adapter, CO2 tank and even bubble counter included! Be careful when using this item. Start rotating one object and you might accidentally lose something else. Use two hands. And if necessary, take pliers to hold or tighten. It worked great right out of the box, as did a Dicks Sports Goods 20-ounce paintball can. **You CANNOT adjust the amount of PSI this regulator delivers to the cone. THE ONLY THING YOU CAN ADJUST ON THIS CONTROLLER is the recirculation flow valve to the bubble counter attached to this controller for the bubbles per second method. The pressure should be between 50 and 64 psi. inches [RIGHT SENSOR closest to bubble counter in image]. The bubble counter can be removed. BUT, again, you can cause another problem elsewhere in the system. On my CO2 system, I just removed the top and plexiglass of the bubble counter to attach the air hose directly to the regulator, bypassing my own. cheap bubble counter to my own custom bubble counter for multiple tank setup. I hope this helps someone who is new to the hobby and doesn't have a manual, just youtube which sometimes doesn't explain enough or show how to do it. Good luck - & - Don't whine
