Controllers & Monitors

Aquarium Fish Tank controllers are a convenient way to keep an eye on the various water parameters in your aquarium. Fish Tank Monitors allow continuous readings of your aquarium's pH, ORP, salinity and temperature. Digital read outs make it easy to see what your tank parameters are at a moment'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), solenoid on CO2 regulators (for pH control) and ozonizers (for ORP control).
*Please keep in mind that ALL sensor probes are pre-tested for accuracy and stored in a saline solution, therefore it is very common to find residue that resembles salt buildup on the probe itself.
