Hygger CO2 Regulator The Hygger CO2 Regulator is an adjustable aquarium CO2 regulator for freshwater planted aquarium systems. It combines dual pressure gauges, a rotatable needle valve, a bubble counter with check valve, and a 12V DC solenoid valve to help deliver controlled CO2 to aquatic plants. Hygger CO2 Regulator Overview This regulator is designed for planted aquariums where stable CO2 delivery supports stronger plant growth and healthier aquascape balance. The dual gauges help monitor cylinder pressure and output pressure, while the needle valve allows fine adjustment of the CO2 bubble rate. The included solenoid valve can be connected to a suitable timer so CO2 can turn on and off automatically with the aquarium lighting schedule. CO2 Regulator Features Dual pressure gauges show cylinder pressure and output pressure for easier monitoring. Green safety range on the gauge helps make pressure readings easier to interpret. Rotatable needle valve allows fine CO2 output adjustment. Bubble counter includes a built-in check valve to help reduce water backflow risk. 12V DC solenoid valve supports automatic on/off control when paired with a suitable timer. Aluminum alloy regulator body provides durable construction for planted aquarium use. Sealing ring at the connection point helps maintain a secure gas seal. Designed for freshwater planted aquarium CO2 systems. Hygger CO2 Regulator Specifications Product type: Adjustable aquarium CO2 regulator UPC: 6976286987516 Model family: HC003 Input voltage: AC100-240V / 50-60Hz Output voltage: DC 12V Gauge design: Dual pressure gauges Valve type: Rotatable needle valve and 12V DC solenoid valve Bubble counter: Included bubble counter with check valve Regulator body material: Aluminum alloy Gauge shell material: Chrome-plated iron Gauge pointer material: Copper Application: Freshwater planted aquarium CO2 systems CO2 Regulator Compatibility Notes The Hygger CO2 Regulator requires a compatible pressurized CO2 cylinder, CO2-resistant tubing, diffuser or atomizer, and a suitable timer if automatic solenoid control is desired. CO2 cylinder, tubing, diffuser, and timer are not listed as included. Use a drop checker or other CO2 monitoring method to confirm the final CO2 level is safe for aquarium livestock. Setting Up the Hygger CO2 Regulator Attach the regulator securely to a compatible CO2 cylinder, install and fill the bubble counter as directed, and connect CO2 tubing from the regulator output to the aquarium diffuser. Open the cylinder slowly, adjust the needle valve gradually, and check all threaded and tubing connections for leaks. Connect the solenoid to the included adapter and timer if automatic daily CO2 control is being used.
