  • Simple design allows safe and effective pH control. The CO2 Feed System maintains the desired pH level by directly injecting carbon dioxide into the water supply. This process creates carbonic acid, which lowers the water’s pH level naturally without hazardous chemicals such as sodium bisulfate, muriatic acid, or sulfuric acid.
  • Completely enclosed in a NEMA 4x enclosure to protect against harsh environments. Simple installation for indoor and outdoor use.
  • Flow adjustment via Blue-White F-440 adjustable flow meter is accurate and consistent, and includes red indicator marker.
  • Simple activation with stainless-steel solenoid valve and illuminated on-off switch.
  • Includes inlet/outlet tubing, and mounting brackets.
