The D-D Advanced ATO maintains the water level in your aquarium, automatically replenishing water lost through evaporation. Its main optical sensor has three detection points allowing the unit to not only control the water level at a set point but also to recognise if the water level is below or above normal, triggering an audio and visual alarm. In addition to the main optical sensor a failsafe ‘Anti Overflow’ float sensor is included that will shut down the ATO function and set off an alert when triggered. An included auxiliary leak detector sensor can also be connected to the ATO and placed next to the sump or the aquarium alerting if any water is detected as a result of a leak or water spillage.
