Abstract: A water change system comprises a water change device that performs automated water changes. The water change device automatically drains an amount of water needing replacement from a reservoir and replenishes the reservoir with a predetermined amount of clean water. The water change device comprises a reservoir port, an output port, an input port, a controller, and an enclosure. In a draining mode, water is pumped from the reservoir, through the reservoir port and into a drain or output tank via the output port. In the reservoir filling mode, clean water from an input tank or water source is pumped into the input port of the water change device and to the reservoir via the reservoir port. The water change device automatically performs water changes in accordance with a water change schedule or in response to user input. The water change device is configurable via a touch display or remotely.
