A liquid discharge apparatus includes a case receiving a cartridge, a tank, a head, and a controller to: when the cartridge is installed in the case, calculate an outflow amount Qc based on heights Hc, Hs and flow path resistances; read the amounts Vc, Vs from a memory; subtract the outflow amount Qc from the read liquid amount Vc to calculate new liquid amount Vc; add the outflow amount Qc to the read liquid amount Vs to calculate new liquid amount Vs; store the calculated liquid amounts Vc, Vs in the memory; after a time period from at the time the calculated liquid amounts Vc, Vs stored elapses, again calculate the outflow amount Qc and the liquid amounts Vc, Vs and store the calculated liquid amounts Vc, Vs in the memory. 1. A liquid discharge apparatus comprising: a first liquid chamber storing a liquid;', 'a first flow path, one end of the first flow path communicated with the first liquid chamber, the other end of the first flow path communicated with the outside; and', 'a second flow path, one end of the second flow path communicated with the first liquid chamber; the other end of the second flow path communicated with the outside;, 'an installation case configured to receive a cartridge, the cartridge including a second liquid chamber;', 'a third flow path, one end of the third flow path communicated with the outside, the other end of the third flow path communicated with the second liquid chamber, at least one of the first flow path and the third flow path configured to communicate with the first liquid chamber of the cartridge installed in the installation case and the second liquid chamber;', 'a fourth flow path, one end of the fourth flow path being below the other end of the third flow path and communicate with the second liquid chamber; and', 'a fifth flow path, one end of the fifth flow path communicated with the second liquid chamber, the other end of the fifth flow path communicated with the outside;, 'a tank includinga head communicated with the ...
