Aquarium Controllers are a convenient way to keep an eye on the various water parameters in your aquarium.  Monitor allow continuous readings of your aquariumâ??s pH, ORP, salinity and temperature. Digital read outs make it easy to see what your tank parameters are at a momentâ??s notice.

A controller is monitor, too, but it also includes an electrical outlet that can be used to turn on or off components like heaters (for temperature control)
