The original N-Fill ATO has been popular with reef keepers. Its new version, the N-Fill Wi-Fi ATO, is now in early access through the ND Lab beta, adding a Wi-Fi controller and NatureBot AI app integration for control, alerts and trends.
Apply for the beta through ND Lab
Please leave a comment here after you submit your application.
We're selecting up to 10 beta testers based on setup and experience. Selected testers receive a unit free to test on their own tank and keep.
Already run the original N-Fill? You can upgrade only the controller and keep your current pump, sensors and other components.
N-Fill Wi-Fi ATO features
- Smart Controller — runs top-off and safeguards locally
- App Control — timed manual top-off and settings in NatureBot
- Notifications & Trends — alerts, top-off frequency, pump runtime
- Dual Float Sensors — two floats monitor the same water level
- Single Top-Off Guard — pump runtime limit for each automatic top-off
- 24-Hour Top-Off Guard — total automatic pump runtime limit over a rolling 24 hours
Eligibility
