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 PRO CO2 System contains the following equipment:

GLA PRO-1-SS [Two Stage] CO2 Regulator

  • High purity, stainless steel, two stage regulator body
  • Dual stage regulator reduces source pressure in two steps to eliminate fluctuation in working pressure, as pressure drops in CO2 cylinder
  • High purity stainless steel diaphragm. Multi-stage stainless steel micron fitration inlet and outlet
  • Stainless steel spring and stem. Stainless steel gauges
  • Laser precision metal-on-metal valve seat. Valve seats - PCTFE, PTFE & Vespel
  • Integrated stainless steel pressure relief valve (PRV)
  • Custom precision GLA needle valve
  • Pro-class solenoid valve with ‘cool touch’ technology keeps the solenoid cool to the touch during operation
  • Custom GLA bubble counter with advanced filtration and check valve to protect internal components of regulator
  • Dual gauge (tank volume and working pressure)
  • No end-of-tank dumps
  • We are confident that our Pro-series GLA CO2 regulators rise above and outlast the competition
  • The innovative modular manifold, allows the user to add manifold blocks with ease, and expand CO2 supply, independently, to up to 5 aquariums
  • Our PRO-series regulators can adapt to the expansion of your aquarium system, allowing you to use one regulator for multiple tanks
  • Our CO2 experts build each regulator to order and provide longterm customer care for each regulator shipped out
  • Custom built, pressure tested, and leak tested in the USA
  • Installation: CGA-320 threads
  • Output Pressure Gauge: 0 - 160 PSI
  • Tank / High Pressure Gauge: 0 - 4000 PSI
  • Integral PRV: Pressure Relief Valve releases at 100 PSI
  • 6 foot electrical cord

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
  • Manual 2 point calibration
  • Double junction pH electrode with 2m cable (BNC connector)
  • Alarm indicates when reading is higher/lower than set point
  • Power Supply: 12 VDC

Two CO2 Cylinders + Manual Cylinder Changeover Assembly + Dual Cylinder Mounting Bracket + Check Valve + Permaseal + CO2 Tubing

  • The changeover system includes two (2) 5lb or 10lb aluminum CO2 cylinders, select the size you need. Cylinders ship empty.
  • The changeover system connects two CO2 tanks with one flexible hose, allowing you to switch between the two connected CO2 cylinders easily, without a service interruption and longer times between refills. Features: Swagelok valve rated at 2500 PSI Core tubing rated at 3250 PSI, heavy duty brass fittings, and Spring guard hose protector for safety and durability.
  • Mount the two CO2 cylinders securely and neatly to a flat surface with the heavy duty 11 guage steel Dual cylinder bracket, with straps and cinch buckle
  • Check valve permits flow in one direction only.
  • Brass permaseal provides a permanent seal for the connection between your CO2 regulator and cylinder.
  • CO2 resistant, high pressure rated tubing. This is not silicone tubing, with our tubing no CO2 will be wasted. Quantity: 10 feet
