Kamoer Launches X2SR Automatic Water Change System


The Kamoer X2SR is designed to be used as an automatic water change system for your aquarium. The X2SR takes the headache out of lugging water jugs back and forth when it’s time to do a water change. Water changes are one of the most time-consuming maintenance tasks (and somewhat annoying) for saltwater aquariums owners. Also there has been plenty of debate over what percentage and how often water should be changed. Some people say it should be weekly or bi-weekly, but few argue against daily water changes. Changing 2% of your water every day will greatly increase your tanks stability and greater potential for a long and successful reefing experience.

Like many modern aquarium devices, the X2SR can be controlled remotely through WiFi with the free Kamoer mobile phone App.

The automatic water replenishment function can be completed through the submersible pump interface. To mitigate possible overflow risks, X2SR comes standard with an anti-overflow sensor. When the water level reaches the anti-overflow sensor, an alarm will be triggered, and the water supply and water change will stop giving you extra piece-of-mind.
