Auto Top Off ATO 😅💧
Honestly, aquarium “evaporation math” is one of those chores that sneaks up on you. One day you’re fine, the next day you’re checking levels like it’s a weather forecast. This Auto Top Off ATO System is designed to help keep your water level steadier so you can spend more time enjoying your tank and less time doing constant top-offs.
Product Explanation
This ATO (auto top off) system uses a high-precision photoelectric liquid level sensor to automatically refill water when levels drop too low. The goal is simple: help maintain more stable water levels in both freshwater and saltwater setups, including reef tanks and sump systems.
It also includes smart safety control with anti-overflow protection, intended to shut off at the optimal water level to reduce the risk of flooding and to help protect your pump from dry running.
