The Niveaumat will automatically top off evaporated water in fresh and salt water aquariums. It comes with an Aqua Medic dosing pump with a directly connected float switch. The float switch is installed in the aquarium or filter tank at the desired level using its holding unit. As the level drops the ato automatically tops off the tank with water from a reservoir. This originally sells online for $140. It comes with everything you see here. $50

I can bring to the swap with me.
