A pumping system (10, 110) includes a pump (16, 116) for moving water. In one aspect, this is in connection with performance of an operation. The system (10, 110) includes a variable speed motor (24, 124) operatively connected to drive the pump (16, 116). A value indicative of flow rate of water is determined and the motor is controlled to adjust the flow rate. A controller (30, 130) is in communication with the motor (24, 124).The controller (30, 130) obtains from a filter menu information including at least pool size and a scheduled time including start and stop times for a plurality of cycles, the controller (30, 130) calculating a filter flow value by dividing the pool size by the scheduled time in order to self-adjust to any total size of the at least one aquatic application (14, 114). The invention is as well related to the corresponding method.
