IceCap ATO EZ Automatic Top-off System

IceCap ATO EZ System
Replenish your aquarium’s evaporated water with ultimate peace of mind using the IceCap ATO EZ System. Designed for simple, reliable operation, this complete kit employs advanced optical sensors and a compact DC pump to automatically top off both freshwater and saltwater tanks.

Key Benefits

  Three optical sensors provide real-time monitoring and safety backups to prevent overflows and pump burnout.
• No Moving Parts
  Optical sensors eliminate mechanical float switches, reducing the risk of stuck components.
• Plug & Play Installation
  Everything you need is included—just position the sensor at your desired water level, place the pump in the reservoir, and plug it in.

How It Works

1. Sensor Mounting
   Position the sensor so that your ideal water level sits between the second and third optical sensors.
2. Pump Placement
   Place the DC refill pump in your reservoir; attach the included hose and run it to your aquarium or sump.
3. Power & Go
   Connect the pump and power supply to the sensor module. When water drops below the low-level sensor, the pump turns on and refills until the normal level is reached.
