Solenoid Valve for CO2 Regulator
A valuable accessory for any calcium reactor.
Attaches inline on the reactor CO2 assembly and plugs into wall. When the power goes off the solenoid shuts down not allowing CO2 to flood your reactor.
This prevents a major pH swing (due to the very low pH in the reactor with so much CO2 present) from happening when power is restored.
Ideal for use with pH Controllers on freshwater planted systems, and marine systems using calcium reactors, etc.
Each solenoid is supplied with a 1.5m cord.
