Abstract:
1. A method for filtering the water of an aquarium, a water cultivation tank or similar water ponds, by means of a filtering system comprising a closed vessel and defining a chamber, a filtering body housed in the chamber, a circulation pump having a suction duct, an outlet of the suction duct being placed in a bottom area of the vessel, and the circulation pump communicating with the aquarium by interposition of a siphon and a delivery duct communicating with the aquarium, and vent means for ejecting air from the chamber, the method comprising the steps of: partially filling the filtering body with a predetermined amount of water; starting the pump; short-circuiting the pump by a fluid passage by putting the delivery duct in communication with the closed vessel; keeping the pump short-circuited at least until the siphon is triggered or activated, to allow water to be transferred from the aquarium to the vessel; subsequently stopping the pump; keeping the pump stopped to allow the air to escape from the chamber and the filtering body to be filled with water; and re-starting the pump once the filtering body is filled with water and the air has completely escaped. wherein a time and a mode of operation of the pump is controlled using a programmable electronic control board.
