The Smart ATO is the smallest and most novel water level sensor and automatic top off controller the hobby has yet seen. The magnetically coupled sensor and controller are one assembly, with a single light sensor being sent through a prism on the wet side of the assembly, inside the sump, to determine high and low water level.
传感器，控制器，泵和大量软管的价格为150美元，智能ATO是您可以获得的最完整和简化的ATO套件。将所有内容都建立在这样的impossibly small devicemakes it easy to keep the ATO system very discrete.
Setting up the Smart ATO is dead simple, and the only reason to crack the very basic instructions is to know what level to initialize the sensor-controller at. The only quirk of the Smart ATO’s function is that ithas在水位以上初始化。否则，Smart ATO只是会发出令人讨厌的“高水位警报”，这不会影响坦克，但是直到您对水位进行调整之前，您不会让您做任何事情。
This high water alarm is problematic during a power interruption, which we simulated, wherein the water level in the sump rises and when the power is restored, the Smart ATO gets started up below the water surface and it screeches for you to do something about it.
Other than that, the Smart ATO is probably the best Auto Top Off system for sensing water level穿过墙壁of the aquarium or sump. With opaque white dreamboxes, and All In One aquarium filters having black walls, the Smart ATO just won’t work and you’ll have to consider other options for ATO functions in these set ups.
On size and simplified function alone the Smart ATO is the iPhone of ATO kits. Most ATO devices and systems are simple enough for regular reefers to install but the Smart ATO is definitely the kind of device we feel comfortable sending our parents home to install on their own tank.
