Aquario Neo CO2 Regulator

The Aquario Neo CO2 Regulator is a dual-stage pressure regulator designed to deliver exceptionally stable CO2 output, eliminating the pressure fluctuations that can harm livestock and plants near the end of a cylinder's life. It connects directly to standard CGA320 or DIN477 CO2 cylinders and features a built-in solenoid valve compatible with timers and pH controllers for fully automated injection schedules. The integrated bubble counter allows precise monitoring of CO2 flow rate, while dual gauges display both cylinder pressure and working pressure at a glance. Constructed from high-quality brass and aluminium components, the Neo Regulator is engineered for long-term reliability in demanding planted tank setups. Compatible with all standard CO2 cylinders from 200g to large 10kg bottles, making it suitable for tanks of any size.
