The Hydor Smart Level Control is a simple device for management of evaporated aquarium water.
The waterproof probe of the Hydor Smart Level Control inserted into the aquarium or sump at the desired level uses temperature difference to figure out where your water level is at, and it turns on a top off pump accordingly.
The automatic top-up provided by the Hydor Smart Level Control is perhaps one of the easiest ways to keep your aquarium or sump with an appropriate amount of water.
