N-Fill Smart ATO System – Dual-Sensor, Advanced Refill Logic, Over-Fill Protection

$69.99 USD
$69.99 USD $69.99 USD
Sale Sold out

Keeps your aquarium water level stable so salinity and waterlines stay consistent with minimal effort. Dual float sensors with built-in redundancy, a quiet DC pump, and an intelligent controller with fail-safe protection work together to deliver reliable, hands-free top offs for both freshwater and reef tanks.

Key Features

  • Dual float sensors and advanced refill logic
    Two independent float switches monitor the same water line. The controller starts a refill whenever either sensor detects low water. Even if one sensor fails, the other still triggers top offs. This redundancy helps prevent missed refills and provides an extra layer of stability compared to most ATOs on the market.
  • Smart over-fill protection
    If the pump runs for more than about 90 seconds, the controller pauses filling and triggers an audible alarm with a red Status LED. This controller-based fail-safe helps prevent overfilling if a float sticks low, flow is restricted, or the reservoir behaves unexpectedly.
  • Intuitive controller with clear status indication
    Three buttons provide simple control:
    • Manual – hold to run the pump for priming or quick refills, release to stop.
    • Pause – press once for a 30-minute pause, ideal for feeding or light maintenance.
    • Stop – press once to disable automatic filling for 24 hours during major maintenance.
    Three LED indicators show system status at a glance:
    • Power – controller has power and is ready.
    • Filling – pump is actively adding water.
    • Status – off during normal operation, blinking when paused, solid red during Stop mode or over-fill alarm.
  • Siphon breaker included
    The included siphon breaker connector and cover help prevent gravity siphoning when the reservoir sits higher than the tank. Combined with the N-Neon ATO Tubing Organizer keeping the outlet above the water surface, this adds another layer of safety.
  • Quiet, compact DC pump
    Small enough to fit common ATO reservoirs while providing sufficient head pressure and flow for most nano and mid-size tanks.
  • Freshwater and saltwater ready
    Designed for long-term use in both freshwater and marine systems, including planted tanks and reef aquariums.
  • UL listed power adapter
    Includes a 12 V 1 A UL-listed power supply for safe and stable operation near water.

  • N-Fill controller
  • Dual float sensors with adjustable holder
