Maintaining stable water levels and conditions is essential for the health of your reef aquarium. Our advanced Auto Top-Off (ATO) system is built with precision, safety, and ease of use in mind, ensuring that your aquarium remains balanced and thriving, even when you’re away.
Key Features:
Triple-Redundant Water Level Protection
Your system uses two high-precision water level sensors in the sump: a primary sensor to maintain the optimal water level and a secondary sensor as an emergency backup. If both sensors were ever to fail, a dedicated float switch immediately disables the pump, preventing overflows or equipment damage. This triple-layer safeguard ensures your aquarium remains protected and stable at all times.
RODI Reservoir Monitoring
A dedicated sensor keeps constant watch over the RODI reservoir. When the water supply runs low, the system alerts you, ensuring your ATO always has enough water for refilling and preventing dry runs.
Advanced Temperature Monitoring & Alarms
A built-in, high-precision temperature sensor continuously monitors your sump’s water temperature. You can easily set your preferred minimum and maximum safe temperature range via the web interface. If the temperature rises above or falls below your set limits, the system immediately triggers an audible alarm and visual warning, alerting you to potentially dangerous conditions. All temperature readings are logged, allowing you to review history and spot trends, helping you maintain a healthy and stable environment for your aquarium.
Easy Maintenance Mode
Maintenance is simple and safe thanks to two dedicated buttons:
- Pause for Maintenance: Instantly suspends all automatic pump operations, allowing you to work on your aquarium without risk of overfilling or equipment interference.
-
Resume Operation: Restores normal automatic function when you’re done.
If you forget to manually resume, the system will automatically exit maintenance mode and resume normal operation after 60 minutes, ensuring continuous protection. While in maintenance mode, the LED indicator glows yellow for easy status identification.
Intuitive Web Interface
Monitor and control your ATO system from anywhere using a modern, user-friendly web interface. Check water levels, view temperature history, adjust settings, set your temperature alarm range, pause for maintenance, and more—all remotely and securely.
Seamless Firmware and Frontend Updates
Keep your system up to date effortlessly. With the built-in firmware update button, you can update both the device firmware and the web-based interface remotely (OTA), directly from the web interface. The system’s LED blinks pink during updates and returns to normal operation when finished, so you always know the update status.
Comprehensive LED Status Indicators
A multi-color LED provides instant visual feedback:
- Green: Normal operation
- Blue: Refilling in progress
- Yellow: Maintenance mode
- Orange: Sump low (warning)
- Red: Emergency/Error
- Magenta: RODI reservoir empty
- White: Startup
These clear indicators help you instantly understand the system’s current status, providing vital information at a glance.
