Kamoer X2SR Auto Water Change System - Pre-order

The X2SR is a twin-head water change pump controlled by an app over WiFi. It takes the routine work out of water changes. One head draws water out of the aquarium and the other puts back an equal volume of fresh saltwater, so the tank level stays steady throughout. It also has a built-in auto top-up that replaces water lost to evaporation, using the included 24V submersible top-up pump.

You can run changes manually or on a schedule, with up to 12 water change programs per day and a set program repeating every 1 to 99 days. The app works on iOS 9.1 and above and Android 4.4 and above. The pumps are driven by stepper motors for accuracy and continuous running. They use 3 roller KCM pump heads fitted with long-life PharMed tubing, and each pump can be calibrated separately. A real-time clock with battery backup keeps the schedule on time. An emergency high-level sensor in the sump sounds an alarm if the water rises too far, and float sensors check whether the fresh water container is empty or the waste container is full. The unit can also work as a two-channel dosing pump.

This suits reefkeepers who want regular, consistent water changes and top-ups without doing them by hand.
