This system is designed to handle routine replenishment automatically, helping reduce day-to-day water additions and the need to ask someone to check the tank during a short trip or business absence. Its dual-sensor control is made to keep the level within the sensors’ operating range rather than relying on a single detection point.\u003c\/p\u003e\n\u003ch3\u003eHow does the MagTool ATO control water level?\u003c\/h3\u003e\n\u003cp\u003eThe lower optical sensor detects when the aquarium water drops and starts refilling; the upper sensor detects the target level and stops the fill. This automatic start-and-stop sequence is designed to help maintain a more stable water level as evaporation occurs. A separate intelligent safety program monitors how long filling runs and stops operation when needed, adding a safeguard against overfilling.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eWater-level detection uses two optical sensors.\u003c\/li\u003e\n\u003cli\u003eThe pump runs automatically when the lower sensor detects a drop.\u003c\/li\u003e\n\u003cli\u003eThe upper sensor signals the system to stop filling at the correct level.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhich aquariums is this auto top-off system for?\u003c\/h3\u003e\n\u003cp\u003eThe MagTool ATO is suitable for reef, saltwater, freshwater, and planted aquariums. It is especially useful for open-top tanks, where faster evaporation can mean more frequent manual water additions. The sensor measures 0.7 inches (about 2 cm), and its low-profile format is designed to take up minimal space and maintain a neat aquarium setup.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFor reef aquariums.\u003c\/li\u003e\n\u003cli\u003eFor saltwater and freshwater tanks.\u003c\/li\u003e\n\u003cli\u003eFor planted aquariums, including open-top setups.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat comes with the MagTool ATO kit?\u003c\/h3\u003e\n\u003cp\u003eThe kit includes the main parts for daily auto top-off operation, including a 12V DC pump measuring 1.5 × 1.5 × 2.0 inches (3.8 × 3.8 × 5.1 cm).
