Kamoer X2SR Auto Water Change Pump

The Kamoer X2SR Auto Water Change Pump is a WiFi-controlled automatic water change system that uses dual high-flow pump heads to remove old aquarium water and add new water on a programmed schedule. Designed for reef, saltwater, and large aquarium systems, it helps automate routine water changes, reduce manual maintenance, and support more stable water quality when properly calibrated and installed.

Kamoer X2SR Automatic Water Change System Overview

Automated water changes without an aquarium controller: The X2SR is designed to handle scheduled water changes through WiFi app control, removing the need to manually siphon and refill small volumes every time. By using two coordinated pump heads, the system can remove used water and add new water according to the programmed volume and schedule.

Built for larger water-change demand: With flow listed at more than 900 mL/min, the X2SR is intended for higher-volume aquarium service compared with small single-head dosers. It is useful for larger reef tanks, fish-heavy systems, maintenance-focused setups, and aquariums where frequent small water changes are preferred over larger manual water changes.

Automatic top-off support: The X2SR can also complete automatic water replenishment through a submersible pump interface, adding more flexibility for aquarium water management. The included anti-overflow sensor is designed to stop water supply and water change operation if the water level reaches the overflow alarm point.

X2SR Auto Water Change Features

• Dual-head automatic water change design: Removes old aquarium water and adds new water through coordinated pump operation.
• WiFi app control: Allows remote schedule setup and water change control through a compatible mobile app.
• High-flow pump output: Flow rate greater than 900 mL/min supports larger water-change volumes than typical small dosing pumps.
• Flexible scheduling: Supports water change or dosing-style intervals from frequent daily operation to less frequent scheduled routines.
• Automatic top-off interface: Includes support for water replenishment through a connected submersible pump.
• Anti-overflow sensor protection: Overflow sensing can trigger an alarm and stop water supply and water change operation.
• Calibration support: Flow calibration helps ensure the water removed and water added stay balanced.
• Large included tubing package: Supplied tubing supports routing between aquarium, waste container, and new saltwater or freshwater reservoir.
• Memory and app-based operation: Designed for repeatable programmed water changes once setup and calibration are complete.

X2SR Compatibility and Installation Notes

Calibration is essential: The Kamoer X2SR Auto Water Change Pump should be calibrated before regular use so the amount of water removed matches the amount added. Uncalibrated lines, reversed inlet or outlet tubing, different line lengths, or incorrect routing can cause water level changes over time.

Use with correct water reservoirs: For saltwater water changes, connect the refill line to properly mixed and temperature-matched saltwater. For top-off use, use freshwater RO/DI water. Do not confuse top-off water with water-change replacement water, especially in reef systems where salinity stability matters.

Plan tube routing carefully: Keep inlet tubing as short as practical, suspend outlet tubing above the tank or sump where required, and use the anti-siphon connector and holders to reduce siphon risk. Confirm lines cannot pull loose, kink, drain to the floor, or continue siphoning when the pump stops.

Setting Up the Kamoer X2SR Auto Water Change Pump

Mount the X2SR in a dry location, connect the old-water removal line, new-water supply line, waste line, and refill reservoir line according to the system layout, then install the float sensor and anti-siphon protection. Pair the pump with the app on a 2.4 GHz WiFi network, prime the lines, and perform flow calibration before scheduling normal operation. Run several supervised test cycles to confirm that water removed and added remain balanced, that the anti-overflow alarm works, and that tubing stays secure during operation.
