IceCap Gravity ATO The IceCap Gravity ATO is a compact gravity-fed auto top-off system that automatically replaces evaporated water in freshwater and marine aquariums without elect ricity. It uses a 500ml bottle, mounting base, inserts, and silicone tubing to provide simple water-level replenishment for small aquariums, nano tanks, and low-tech top-off applications. IceCap Gravity ATO Overview This ATO is designed for aquarists who want a simple non-electric top-off solution. The bottle threads into the base and uses water pressure differences to release water when the aquarium level drops below the shorter tube. Because it does not use sensors, pumps, controllers, or power cords, it is best suited to small systems where a compact reservoir and straightforward mechanical operation are preferred. Gravity Fed ATO Features Automatically replaces evaporated water without electricity, sensors, or a pump. Compact 500ml bottle format is useful for nano aquariums and small systems. Works in freshwater and marine aquariums when filled with appropriate top-off water. Gravity-fed operation begins when water level drops and exposes the shorter tube. Includes three mounting inserts for different aquarium rim sizes. Silicone tubing can be cut to set the desired operating water level. Simple design reduces wiring and equipment clutter around small aquariums. IceCap Gravity ATO Specifications Product type: Gravity-fed aquarium auto top-off system UPC: 6972809520826 Manufacturer SKU: IC-GATO Bottle capacity: 500ml Operation type: Non-electric gravity-fed top-off Included mounting inserts: 3 Application: Freshwater and marine aquarium evaporation replacement Power requirement: None Gravity ATO Compatibility Notes The IceCap Gravity ATO is best for smaller aquariums where 500ml of top-off capacity is appropriate. For saltwater aquariums, use freshwater top-off water to replace evaporation, not mixed saltwater. Confirm the rim insert fits securely, make sure the bottle is stable, and monitor the system during initial use so the water level is set correctly. Setting Up the IceCap Gravity ATO Select the mounting insert that fits the aquarium rim, insert it into the Gravity ATO base, and cut the silicone tubing to set the desired water level. Cut the long and short tubes at a slant, insert them into the base, fill the bottle with appropriate top-off water, thread the bottle into the base, and mount it on the aquarium rim. Adjust the tube position so the ATO replenishes water when the level drops below the shorter tube.
