Enjoy Your Aquarium, Not Another Refill Chore

 

Spend more time watching your underwater world and less time topping up evaporated water. This aquarium auto top-off system monitors the waterline and activates a refill pump when needed, helping maintain a more consistent level in freshwater, reef, and sump setups.

The compact sensor sits discreetly at the waterline, while its magnetic mount makes positioning and adjustments convenient. Choose the Blue or Green-1 option for your setup.

Compact Control for Everyday Care

  • Dual optical sensor: Combines an ATO level sensor with a secondary failsafe sensor to monitor water levels.
  • Automatic refilling: Uses the included pump to move top-up water from a separate reservoir into the aquarium.
  • Magnetic mounting: Lets you reposition the sensor to set the desired fill level.
  • Small footprint: The listed sensor diameter is approximately 0.7 inch.
  • Operating safeguards: Built-in monitoring is designed to help protect against overfilling and pump dry running.
  • Status indicators: Visual indicators provide operating status and alerts.

What’s Included

Refill pump, tubing, sensor assembly, and installation components. The product pictures also show a tube holder and check valve.

Product Details & Setup

  • Type: automatic aquarium top-off system
  • Model marking on pictured packaging: AT-200 Smart ATO Lite
  • Options: Blue and Green-1
  • Intended use: replacing evaporated water in freshwater and reef aquarium setups
  • Mounting: magnetic sensor attachment

 

Before use: Check compatibility with your aquarium wall and layout, then follow the included installation instructions. Use a separate refill reservoir, keep it adequately filled, and secure the tubing as directed. Inspect the sensor, pump, and tubing regularly. Automatic top-off supplements rather than replaces routine water-level and aquarium monitoring.
