{"product_id":"n-fill-ato","title":"N-Fill Smart ATO – Dual Sensor, Advanced Refill Logic, Over-Fill Protection","description":"\u003cp\u003eKeeps your aquarium water level stable so salinity and waterlines stay consistent with minimal effort. Dual float sensors with built-in redundancy, a quiet DC pump, and an intelligent controller with fail-safe protection work together to deliver reliable, hands-free top offs for both freshwater and reef tanks.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual float sensors and advanced refill logic\u003c\/strong\u003e\u003cbr\u003eTwo independent float switches monitor the same water line. The controller starts a refill whenever either sensor detects low water. Even if one sensor fails, the other still triggers top offs. This redundancy helps prevent missed refills and provides an extra layer of stability compared to most ATOs on the market.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptional sensor arm extension for deeper tanks\u003c\/strong\u003e\u003cbr\u003eAdd the Extra Sensor Arm Extension when the standard sensor arm does not reach the desired water level. The accessory adds approximately 5 in (13 cm) of mounting depth, extending the total sensor reach to approximately 10 in (25 cm) below the tank rim, depending on the installation. The sensor cable split connector must remain safely above the highest possible water level and must not be submerged.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmart over-fill protection\u003c\/strong\u003e\u003cbr\u003eIf the pump runs for more than about 90 seconds, the controller pauses filling and triggers an audible alarm with a red Status LED.
