Decided to purchase a hydro wizard ecm 75 from Germany . I placed the order last night and should get it on 24 th November . I am trying to figure out a way to mechanically move the pump up and down the entire height of the aquarium ( approx 3m) . I have spoken to the elevator 's technician of linking the signal from the elevator to the pump's housing so that when a passenger in the elevator presses the button up or down , the pump will move up and down accordingly so as to create a random motion of waves and hotel's guests become part of the life supporting system of the aquarium. Linking the signal is the easy part but to find a mechanical process of moving the pump under sea water ( very corrosive) is the difficult part .
