Description
xMeet the FZONE Aquarium ATO Auto Top Off System, a compact, reliable solution designed for both reef and freshwater tanks. The 360P model features a nano profile of only 0.7 inches and is suitable for rimed, rimless aquariums or sumps, helping you tuck the unit away in tight spaces while keeping the display area clean and accessible.
Two 1 mm precision optical sensors monitor the water level in real time, delivering continuous feedback that keeps water level fluctuations under 0.6 cm. This precise sensing supports a steadier evaporation compensation and helps your equipment maintain a more consistent environment without daily manual adjustments. The system is quiet by design and aims to minimize surprises when you wake up or come home after work.
Smart fill dynamics are at the heart of this ATO. EFTT (Extended Fill Time Technology) analyzes tank size and estimates how long it will take to reach the target level. If the required fill is unusually long, QST 2.0 provides a real time visual alert and prevents over filling. AFT (Anti-fluctuation Technology) reduces pump activation when it is not needed, contributing to lower wear and quieter operation over time. Together, these technologies offer a balanced approach to maintaining stable water levels across different evaporation rates and tank sizes.
The 360P also offers real-time protection against overfilling and pump run dry. If a sensor, controller or reservoir malfunctions or runs low, the ATO alerts you and stops the pump to avoid unintended events. The upgraded QST 2.0 includes new safety features that enhance reliability for daily use, helping you feel more in control of water management even during extended absences.
Everything you need ships in the box. The included magnets support aquarium walls up to 0.78 inches (20 mm) thick, a check valve blocks backflow so the main display does not drain, and the 74 GPH pump can lift water up to 2 meters, ensuring dependable top-off for larger tanks. The combination of a compact form factor and a capable pump makes it suitable for a wide range of setups, from nano systems to mid-size displays.
FZONE backs this product with round-the-clock customer service. The team is available for product related questions or concerns, helping you get the most from your setup while you monitor your tank conditions. This support is designed to complement the intelligent hardware for a smoother, more productive aquarist experience.
