The Fzone Pro Series are a professional grade regulator for injecting Co2 in home aquaria. As the compressed CO2 gas inside the cylinder is running low pressure, a single stage regulator has a much higher risk of letting off a huge volume of CO2 gas. A Dual Stage construction prevents E.O.T.D. (End Of Tank Dump) allowing you to maintain stable CO2 output & saturation. High precision needle valves & built-in check valves leaves you to relax knowing your livestock is safe & providing an opportunity to focus on more important area's of your tanks functionality.

In nature fish & plant life coexist in a balance beneficial to both; The plants thrive on the waste produced by the fish & the fish take cover in the flora. However, too much or too little CO2 will affect both plants & fish. Lack of CO2 will display pale leaves & stems, or stunted growth. This also means that the plants will be unable to properly saturate the water to provide more oxygen for your livestock. Too much Co2 can also having a damaging affect on livestock ultimately resulting in death. These issues are best avoided with the use of a drop checker & PH Pen/Monitor to keep livestock & plants thriving. CO2 plays a vital role in the life of fish. Too much or too little will not only harm the fish but may lead to the untimely death. A CO2 regulator ensures the level of CO2 is at proper saturation. Co2 will also minimize the negative effects of Algae. Algae is one of the biggest threats for plants & fish it can cause loss of plants & block gaseous exchange preventing your livestock from uptaking oxygen. Installing a Co2 system in the aquaria for injecting & monitoring carbon dioxide will ensure you have the proper saturation of both O2 & Co2. 


  • Dual stage construction provides stable output pressure regardless of how much CO2 gas remains inside the CO2 cylinder, eliminating unpredictable catastrophes such as an end-of-tank-dump (EoTD).
  • Dual gauge indicates tank volume & working pressure
  • Safety valve built in. When the pressure exceeds 100 PSI, the valve will automatically release the pressure
  • Pressure knob is adjustable from 0-65 PSI depending on your plants needs
  • Expandable manifold blocks with integrated high precision needle valves (run 6 aquariums on one regulator) 
  • High performance DC 12V solenoid valve low power consumption (won't overheat)
