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 Brooke Gill

Reasonably priced product and didn't take me long to assemble. There were no instructions in my package but when I emailed them they wrote it for me. I've included their build instructions at the bottom of this review for anyone like me who has never installed CO2. My main reason for giving 5 stars is the customer service. I had several questions and each time they were quick and friendly in their answers. Instructions: 1. When connecting the regulator, the tank will open. high pressure in the regulator housing. DO NOT disassemble the controller.2. The operating pressure is preset, you only need to set the needle valve for flow. DO NOT rotate the handle (part of FZ logo).3. After power off, the regulator will continue to emit bubbles for 5-15 minutes. This is normal (not a defect). since high pressure CO2 takes time to be released.4. Before installation, check the correct position of the O-ring. Otherwise, leakage may occur. If your tank is paintball. Color adapter required.6. If a paintball tank. Install the adapter on the controller first.7. If a paintball tank. Remove the regulator, you must remove the adapter along with the regulator.
