Water changes are essential for maintaining a healthy aquarium, but they can be time-consuming and labor-intensive. Siphoning out the old water, carrying buckets, carefully adding new water...this process requires significant effort and attention to detail, making it a tedious and sometimes messy task. The Smart AWC Lite automates this process, ensuring precise and consistent water quality with minimal manual intervention. It simplifies the task, saves time, and reduces the likelihood of errors that can occur with manual water changes.


Integrated Diaphragm Pump

The Smart AWC Lite has a diaphragm pump integrated right into the controller, making for a compact design with fewer wires. Different from a submersible pump, a diaphragm pump has the benefit of being able to run dry without damage. There is a built-in anti-siphon valve as a safeguard.

Precision Engineered Sensors

The enhanced optical sensors in the system offer highly accurate water level detection, capable of sensing changes as minute as 1mm, while also reducing false alarms. For added reliability, each sensor comes equipped with a main sensor and a fail-safe backup, ensuring continuous protection for your aquarium in case the primary sensor encounters any issues.

Integrated Auto Top Off System

The Smart AWC Lite System utilizes the high level sensor as an ATO sensor, allowing the system to perform auto water changes without interfering with the auto top off system.

Product Questions

Hi, my ATO alarm constantly turning on instead toping up my tank. Any suggestions?
Question by: Viktor Katona on Mar 14, 2024, 1:55 AM
The sensor might be malfunctioning or need to be cleaned. If cleaning doesn't solve the issue, you way need to replace the sensor. CoralVue may have the replacement parts if needed.
