This package includes two products that will work together to create an auto top-off system. We pair the IceCap 5 Gallon Freshwater ATO Reservoir with the IceCap ATO EZ System. We throw in the MarineAndReef.com pH Tester because everyone needs a pH Tester.

This IceCap Freshwater Reservoirs holds 5 gallons of water. The reservoir is fully enclosed to prevent dust and debris from entering and to minimize evaporation. It features a float valve for refilling directly from the reverse osmosis unit.* It includes two 1/4 inch quick-connect fitted intakes for ATO applications, and will work perfectly with the IceCap ATO EZ System.

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 Reservoir also has a convenient micro-dosing line for automated testing machines such as the HYDROS Maven. The reservoir has a large service opening with a lid for easy refilling and full access to the interior of the reservoir.
