The Simplicity Easy-Fill ATO Reservoir elevates and simplifies the water top-off routine. The patent-pending, wide-mouth lid converts to a funnel for easy refills, allowing users to spend less time on maintenance and more time enjoying their aquarium. The reservoir keeps salinity and water level consistent while shielding the water from external elements and evaporation loss. These one-of-a-kind top-off containers are available in two space-saving sizes and covered by a 3-year prorated limited warranty and unlimited lifetime, US-based support.
