Description
The Neptune Systems ATK V2 Auto Top Off Kit is a complete system for automatically replacing freshwater lost to evaporation. It can operate as a standalone ATO without an Apex controller or connect to an Apex system for additional monitoring, alerts, and integration through Apex Fusion.
The ATK V2 uses two optical water level sensors, IQ-Fill runtime intelligence, and a mechanical float valve to provide three layers of overfill protection. The included PMUP v2 delivers top-off water from the reservoir to the aquarium or sump, while the magnetic mounting assembly keeps the sensors and float valve together in one compact installation.
Key Features
- Complete standalone auto top off system
- No Apex controller required for basic operation
- Two optical water level sensors
- IQ-Fill learns normal top-off runtime and helps prevent overfilling
- Mechanical float valve provides an additional physical backup
- Built-in audible failure alarm
- Includes PMUP v2 utility pump
- Connects to Apex for notifications and additional automation
Three Levels of Overfill Protection
- Backup Optical Sensor: Stops the pump and sounds an alarm if the primary sensor fails to stop the top-off cycle
- IQ-Fill: In standalone mode, monitors normal top-off runtime and stops the pump if a cycle runs unusually long
- Mechanical Float Valve: Provides a physical backup to stop incoming water if the electronic safeguards fail
