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

Milwaukee MC122 PH Controller

The Milwaukee MC122 pH Controller allows you to monitor pH andmaintain 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.

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

Excellent system

Purchased this system for my 100 gallon tank at work (my first foray in CO2) and was so impressed with it that I bought a second identical system for my tank at home. The setup was relatively easy with clear instructions. The PH controller works like a charm. Since I got it up and running the plants are growing like crazy, and I haven't had to adjust anything. It's expensive, but I feel it is well worth the money. I had an issue with my diffuser not functioning correctly initially on the first system, but the company sent me a replacement by priority mail immediately. Before the replacement arrived the diffuser started diffusing (probably a stuck check valve). Impressed with GLA.
