Kamoer X2SR Auto Water Change Pump

The Kamoer X2SR is a WiFi-controlled automatic water change system: one pump drains old water to a waste container while a second pump refills the tank with fresh saltwater, on a schedule set from your phone.

• Pump flow: 900+ mL/min; max head pressure 32 ft
• Scheduling: from 24 doses/day down to 1 dose per 99 days
• Includes float-level sensors for low freshwater and full-wastewater detection, plus a dedicated anti-overflow sensor that halts the pumps and alerts if a tank reaches a warning level
• Dimensions: 168mm L x 177mm W x 223mm H (excluding power adapter); approx. 4.1kg
• WiFi: 2.4GHz only (not compatible with 5GHz-only networks)
• Power: DC24V 1.9A, 100-240VAC universal input

Manual water changes are one of the most-skipped reef tank maintenance tasks precisely because they're tedious — hauling buckets, mixing salt, matching temperature. Automating the drain-and-refill cycle on a schedule removes that friction, and the layered float-sensor and anti-overflow protection is what makes leaving it unattended reasonable instead of risky.

Includes: X2SR unit, DC24V power adapter (US/UK/EU/AU plugs), 6m of 9.5mm ID / 12.5mm OD tubing, 1.5m of 8mm ID / 11mm OD ATO tubing, manifold connectors, float level sensors with brackets, submersible pump, 50mL calibration cylinder, anti-siphon connector.
