A liquid discharge apparatus includes: an installation case receiving a cartridge including a first liquid chamber; a tank including a second liquid chamber; and a controller configured to: when the cartridge is installed in the installation case, determine a liquid amount Vs of liquid stored in the second liquid chamber based on an outflow amount of liquid flowed out from the cartridge toward the tank and a discharge liquid amount for performing image recording of unit recording area; when the liquid amount Vs reaches a first threshold, determine a first recording speed as a recording speed; when the liquid amount Vs does not reach the first threshold, determine a second recording speed slower than the first recording speed as the recording speed; and perform the image recording of unit recording area at the determined recording speed.
