AquaAuto Smart Mini ATO


  • Description
  • Specifications

The Mini ATO top up system comes in either a single float switch or dual float switch models.

Both models have the main function of topping up your aquarium water using the included 'Anti wave level sensor(s)' to determine when to add further water from your reservoir (not supplied) to your fish tank. This helps avoid evaporation issues and tops up your aquarium water level to the point you have set the sensor to.

All you have to do is ensure your reservoir is filled at all times. When the reservoir is running low on water, the ATO will chime to let you know that a refill is needed.

The float switches (Anti wave level sensors) are extremely robust and due to the way they are encapsulated will avoid the wear and tear typical on other versions of these products. 


The reason for offering two models (one or two sensors) is that the MATO-200P has the additonal feature of avoiding pump burn out by only allowing your pump in the reservoir to pump water to your tank if it is fully submerged at all times.


Please note: This item includes EVERYTHING you need except for a water reservoir.
