1. A peritoneal dialysis system comprising:
a cycler including a control unit and a pump actuator under control of the control unit; and
a disposable set operable with the cycler, the disposable set including
a pumping cassette having a pump chamber configured to be actuated by the pump actuator, and
a mixing container in fluid communication with the pumping cassette,
wherein the control unit is programmed to promote mixing of at least two fluids by (i) causing the pump actuator to operate the pump chamber to pull the at least two fluids from the mixing container into the pump chamber, (ii) thereafter causing the pump actuator to operate the pump chamber to push the at least two fluids from the pump chamber to the mixing container, and (iii) repeating (i) and (ii) at least one time, and
wherein the mixed at least two fluids form a volume and in (iii), (i) and (ii) are repeated until a certain percentage of the volume is pulled and pushed by the pump chamber.
