Each float sensor has been designed with an exterior guard preventing snails & hermit crabs from attaching to the sensors.

Our compact controller also incorporates a visible L.E.D. panel and an Audible Signal alerts when in operation mode.
The kit includes commercial grade “Linkable Brackets” that can easily be adjusted to meet your height requirements, and securely positions your float sensors. No suction cups to lead to disastrous water spillage.
Pump Safety Protection
The A.T.O. automatically stops power to your return pump in your reservoir, in the event that your reservoir is low on water. This safety feature prevents pumps from running dry and failing. (Mode A- Example 1)
Note: No pump included. The pump will need to be able to refill the amount of evaporated water in just a couple of minutes. BRS suggest purchasing a pump that is just slightly larger and placing a ball valve to control the overall amount of flow. We suggest looking into the Sicce Syncra Silent line of pumps or the BRS 50 mL top off pump.
