Aquarium Controllers & Monitors

Aquarium controllers are a convenient way to keep an eye on the various water parameters in your aquarium. Monitors allow continuous readings of your aquarium’s pH, ORP, salinity and temperature. A controller is monitor, too, but it also includes an electrical outlet that can be used to turn on or off components.
