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.
