Fish Tank Smart Refill

Electronic Sensor Type (More Precise)
Uses water level probes to detect the water level:
When the water level is below the probe, the controller activates a small pump to add water from a reservoir.
When the water reaches the set level, the probe triggers the pump to shut off automatically

About this item
Small in size; install in a compact space, install in both rimed & rimless aquariums or sumps. ATO is nano at only 0.7 inches.
Includes <1mm dual precision optical sensors, watches the water level in real time, ensures the aquariums water fluctuation is less than 0.6 centimeters. New technologies that allow the ATO to be more reliable; EFTT(Extened-Filling-Time Technology), AFT(Anti-fluctuation Technology) techology, & upgraded QST 2.0 (Quick-Security Technology). EFTT can recognize your aquariums size & will dertimine how long it takes to fill to the desired level. QST alerts you in real-time when the ato is finished & prevents over filling. AFT measures the water level & ensures the ATO doesn't activate the pump unnecessarily. QST 2.0 provides real-time protection against overfilling & won't allow the pump to run dry. The ATO controller will give a visual alert & stop the pump immediately when it senses a refilling time more than 6 times longer than the time calcualted by EFTT. QST will detect malfunctions of the sensor, controller or if you have a empty reservoir. Version 2.0 includes new technology making our ATO’s the most safe option. All accessories included in the package. Strong magnets can support aquarium wall thickness up to 0.78 inches (20mm). Check valve prevents backflow & will not drain your main display. 74 gallon per hour water pump will lift water up to 2 meters ensuring water delivery to even the biggest aquariums.

Application Scenarios of Water Replenishers Water replenishers (including automatic/pressure-fixed water replenishment devices) are used in aquarium, HVAC, industrial, civil, agricultural, and special equipment fields. Their core functions are to automatically maintain stable water level/pressure, compensate for evaporation and leakage, and ensure continuous system operation. I. Aquarium & Pet Breeding (Most Common Civil Scenarios) • Fish tanks/aquariums: Automatically replenish water lost to evaporation, maintain water level, and prevent dry burning of heating rods and water pumps; suitable for long-term unattended use (business trips, travel). • Reptile terrariums: Provide stable humidity and drinking water level for lizards, snakes, frogs, etc. • Mini waterscapes/paludariums: Maintain landscape water level and reduce manual maintenance. II. HVAC & Heating Systems (Core Industrial/Commercial Scenarios) • Central air conditioning systems: Circulate chilled/cooling water, compensate for evaporation and blowdown loss, stabilize pressure, and ensure cooling efficiency. • Central heating/underfloor heating: Used in heating circulation for residential quarters, villas, and office buildings to stabilize pressure, prevent overpressure and leakage, replacing high-level expansion tanks. • Boilers/heat pumps/solar water heaters: Automatic water replenishment and pressure stabilization to avoid water shortage, vaporization and pipeline rupture. • Hot water systems in hotels/hospitals/schools: Stabilize water pressure and temperature to avoid sudden temperature changes. III. Industrial Production & Cooling Systems • Industrial circulating cooling water: Used for water replenishment and pressure stabilization in cooling systems of reactors, compressors, heat exchangers and data center rooms in chemical, metallurgical, electronic, pharmaceutical and food processing industries. • Process water systems: Maintain continuous and stable water level/pressure for production lines in textile, paper making, electroplating and other industries. • Power plants: Water replenishment for boilers and pressure stabilization for circulating cooling systems. IV. Civil & Building Water Supply • Secondary water supply in high-rise/residential areas: Replace roof water tanks, stabilize water pressure, and avoid water outages and water hammer noise. • Fire water supply systems: Maintain pipe network pressure to ensure reliable water supply in case of fire. • Rural/temporary water supply: Pressure-stabilized water replenishment for construction sites, field operations and rural tap water. V. Agriculture & Landscaping • Greenhouse irrigation: Automatic water replenishment to maintain water level in nutrient solution tanks/water tanks for drip irrigation and sprinkler irrigation. • Gardens/fountains/waterscapes: Stabilize water pressure to ensure fountain effects and compensate for evaporation and leakage. • Aquaculture: Automatic water replenishment for fish and shrimp ponds to maintain stable water level and quality. VI. Other Special Scenarios • Laboratories/clean rooms: High-precision water replenishment and pressure stabilization for constant temperature and humidity air conditioners and ultrapure water systems. • Humidifiers/steam equipment: Automatic water replenishment for industrial humidifiers and steam generators. • Energy storage/battery cooling: Water replenishment and pressure stabilization for liquid-cooled energy storage systems and power battery test benches.
