Sumpless ATO2 Auto Top Off System (OPEN BOX)

No sump, no problem! An ATO system designed for aquariums without sumps 

• New Controller programming for added protection
• New sensor design for increased longevity
• Built-in backup sensor
• Provides surface skimming
• Media Chamber for filtration media

The Sumpless ATO2 is the ultimate ATO solution for aquariums without sumps. It incorporates a stylish overflow box and a dual-optical sensor ATO that will ensure your aquarium is always filled to the correct water level. A must-have for maintaining a stable salinity level for your tank inhabitants.

Thanks to its magnetic mount, the overflow box can easily be fixed to any aquarium with glass thickness of up to 1/2" thick. It serves as a surface skimmer that efficiently removes that unwanted film from the water's surface, while also doubling as a reactor for media like carbon and GFO.

XPAqua's dual-optical sensor includes two precise level sensors. The ATO pump is activated when the water level drops below the primary sensor, then stops when the water level reaches the sensor. To avoid overfilling, the secondary sensor acts as a backup to shut off the ATO pump in the event there is an issue with the primary sensor.
