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 helps to keep 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 5 and 10 gallon space-saving sizes.

Simplify Maintenance: The one-of-a-kind easy-fill lid with built-in splash guard allows users to quickly fill the reservoir with less mess.

Universal Compatibility: It pairs easily with nearly every auto top-off (ATO) on the market. The lid's large opening fits most ATO pumps and features tubing and power cord cutouts.

Reduce Algae Build-up: Opaque black sides help prevent light penetration and reduce nuisance algae growth.

Track Top-Off Usage: The clear acrylic front panel with easy-to-read graduations lets you view the volume at a glance.

Space-saving Design: The compact footprint fits easily inside most cabinets.
