Photo sensor that will allow the Tunze 7090.050 controller which is now included with all Tunze Nanostream and Stream pumps to turn off at night when no light is available and then turn back on when your light is on.
When no light is available the 7097.050 photo sensor will turn your pumps off automatically by picking up how much available light is being picked up by the sensor. When the light is on the pumps will ramp up to follow the max settings on the controller. The photo sensor should be placed directly under your tanks lights and will follow the photo period of your light.
