1. A metering unit (100) for the controlled supply of a substance inside an aquarium tank (10), comprising:
a containment box (110);
a dosimetric pump (200) which is actuated by an electric motor (300), both being associated with the containment box (110); and
a printed circuit board (400) which is positioned in the containment box (110), the printed circuit board (400) comprising at least one electrical contact (401) which faces at least one opening (115) which is present in the containment box (110) in such a manner that the at least one electrical contact (401) of the metering unit (100) is associated with a respective electrical contact of a similar metering unit;
the containment box (110) having at least a first connection element (111) and at least a second connection element (112) connectable to a corresponding first connection element (111) of an additional similar metering unit in such a manner that the metering unit (100) can be connected in a modular manner to the additional similar metering unit, wherein there are present on a first end (411) of the printed circuit board (400) a plurality of electrical contacts (401) which face respective openings (115) in the containment box (110), the electrical contacts (401) on the first end being in numbers corresponding to the respective openings (115), and, on a second end (412) of the printed circuit board (400), a plurality of electrical contacts (401) which face respective openings (115) in the containment box (110), the electrical contacts (401) on the second end being in numbers corresponding to the respective openings (115).
