Too much CO2 can reduce the pH in an aquarium to levels that are stressful for fish. For the safe use of CO2 it is highly recommended to automate the CO2 system with either a simple time switch or by a pH controller. The in-line solenoid Control Valve connects the CO2 system with either of these devices. Includes both a hose barb with lock nut for in-line connection on the CO2 tubing and a standard 1/8√∂ thread for direct connection to a pressure reducer.
