Replenish Evaporated Water... with Confidence!

The IceCap ATO EZ System is an easy-to-use pump and sensor combo that offers peace of mind when replenishing evaporated water to an aquarium. Its twin optical sensors extend the device’s life and reliability by limiting the frequent powering on and off of the refill pump. This system also includes a third (safety) sensor that provides another level of security to prevent overflows.

The IceCap ATO EZ is a well-thought-out automated system with a fail-safe design that uses two (2) optical sensors to monitor the fluid level of your aquarium or sump. The third optical sensor provides real-time protection against the failure of the second sensor. Best of all, it is very easy to install and contains no moving parts that can fail.

Complete Auto Water Top-off System for Fresh and Marine Aquariums

Everything is provided for installation and operation. You simply move the magnet optical sensor to the desired water level within your sump or aquarium. It’s that easy!

ATO EZ Operation

When the water level in the sump or aquarium drops below the LOW LEVEL (3) on the sensor, it will blink blue until the water level rises to the NORMAL LEVEL (2).

When the NORMAL water level resumes, a solid blue light will display.

SAFETY LEVEL SENSOR (1) is a backup to shut down the feed pump in case of a malfunction; in this case, a red light will flash.
