The AutoAqua Smart ATO Lifter is a premium auto-top-off system designed to automatically replenish evaporated water in your aquarium, maintaining a stable salinity level critical for the health of your reef inhabitants. This system combines a brand new, highly accurate controller with a silent AQUA Lifter Pump to deliver precise and regular water additions. Its clever shape and neat, compact design ensure it integrates seamlessly into any setup without being obtrusive.

This ATO features a magnetically coupled optical sensor that is merely a quarter-inch thick and can be mounted on clear, tinted, or painted surfaces up to a half-inch thick. The sensor functions reliably in both daylight and complete darkness, making it perfect for concealed placement in a cabinet or rear sump chamber. The system includes a replaceable diaphragm pump that adds water slowly for accuracy, a built-in anti-siphon valve to prevent backflow, and Quick Security Technology (QST) which provides audible and visual alarms in case of failure.

The Smart ATO Lifter is an excellent choice for owners of compact or all-in-one aquariums where space is at a premium. Its user-friendly controls, versatile mounting options for both the pump and sensor, and quiet operation also make it ideal for any aquarist seeking a reliable, easy-to-install, and low-maintenance solution for water level management. Hobbyists who prioritize safety and precision will appreciate the built-in security features and the slow, controlled water delivery.
