More Info Close
Product Highlights
  • Required To Regulate Co2 Flow Accurately --- In order to properly monitor and adjust the flow of CO2 in your fish tank or aquatic plant environment, a CO2 diffuser set is necessary. An essential part of any functioning diffuser setup is a dependable adjustment valve. The Rhinox CO2 Needle Valve regulates the amount of CO2 that should be released into your aquarium water.
  • For Optimal Development Of Inhabitants --- All plants undergo a photosynthesis process that requires CO2 which they convert into oxygen. Your fish, shrimp, and other aquatic pets need to inhale this oxygen in order to survive and also exhale the carbon dioxide. Monitoring and regulating the amount of CO2 in your aquarium is essential to growing happy aquatic plants and pets.
  • Durable Stainless Steel Interior With Aluminum Alloy --- this valve is constructed with high-quality, reliable stainless steel and aluminum alloy. The Aquarium C02 Regulator Needle Valve is lightweight and easy to operate. The precise structure of the needle valve features a special metal grinded surface and finely detailed threading for secure closure.
  • Quick & Easy To Setup And Install --- Ergonomically designed, the CO2 regulator valve quickly and easily installs into your CO2 diffuser set without the use of any additional tool. The practical nut lock design effectively locks the one way valve to the CO2 tube without any worry of coming loose or causing mishappenings.

FZONE Pro Series Aquarium Dual Stage CO2 Regulator Adjustable Output Pressure with DC Solenoid and Integrated High Precision Needle Valve and Bubble Counter
More Info Close
Product Highlights
  • Dual stage construction & adjustable output pressure. 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). The output pressure is adjustable from 0-65 PSI based on customers’ different needs.
  • Modular manifold block design. Two manifold blocks are included. Each block comes with its own high-precision needle valve and can be operated independently. You may use one block for one aquarium or use both for two aquariums.
  • Safety and precision in mind. Our regulator has a built-in safety valve. It will open automatically to release the pressure when it exceeds 100 PSI. The integrated needle valve is precise. The CO2 output can be adjusted to as low as 1 bubble every 3 seconds.
  • Solenoid runs on 12V DC instead of conventional 120V AC. This regulator adapts to 12V DC, which is more stable and consumes less power. The solenoid is safe to touch and is very quiet. This solenoid is designed to work with an automatic timer.
