This pH control crossover switch is specifically designed to be used in swimming pool and aquatic applications where both CO2 and acid are used to control pH levels. The pH control crossover switch allows for a simple flip of the switch to change from using acid to CO2 – no need to unplug one feeder and plug in a different feeder.
