GLA custom CO2 systems provide planted tank hobbyists the CO2 essentials and monitoring equipment they need to grow a successful planted tank. Our extremely reliable CO2 equipment allows you to focus on what's important, growing & enjoying your planted tank. The GLA MINI-SS CO2 System contains the following equipment:

GLA MINI-1-SS CO2 Regulator

The GLA MINI-series CO2 regulators lead the way in adaptive CO2 distribution. Our innovative modular manifold, allows the user to add manifold blocks with ease, and expand CO2 supply, independently, to up to 5 aquariums. Our MINI-series regulators can adapt to the expansion of your aquarium system, allowing you to use one regulator for multiple tanks. We make sure that when you invest in our professional CO2 equipment, you invest in a single regulator that can grow with you and last a lifetime.

Milwaukee MC122 PH Controller

The Milwaukee MC122 pH Controller allows you to monitor pH and maintain desired CO2 levels in your aquarium. The MC122 is designed to connect to the solenoid of your CO2 regulator. It regulates the release of carbon dioxide, which is directly related to pH. Once a desired pH is set, the controller will signal the solenoid valve to prompt the CO2 regulator to stop releasing or to release more CO2 in order to maintain the set pH.

  • Range: 0.0 ~ 14.0PH
  • Accuracy: ±0.2PH
  • Resolution: 0.1PH
  • User selectable Hi/Low Set Point
