EFTT can recognize your aquariums size & will dertimine how long it takes to fill to the desired level. QST alerts you in real-time when the ato is finished & prevents over filling. AFT measures the water level & ensures the ATO doesn't activate the pump unnecessarily.

Check valve prevents backflow & will not drain your main display. 74 gallon per hour water pump will lift water up to 2 meters ensuring water delivery to even the biggest aquariums.

The ATO controller will give a visual alert & stop the pump immediately when it senses a refilling time more than 6 times longer than the time calcualted by EFTT. QST will detect malfunctions of the sensor, controller or if you have a empty reservoir. Version 2.0 includes new technology making our ATO’s the most safe option.
