Smart ATO RO is a reliable device to fill your RO or RO/DI water reservoir automatically. When the water level falls down to the low-level sensor, it will fill the reservoir up to the high-level sensor. You can avoid TDS creep in the reservoir and always get clear RO or RO/DI water for your aquariums but never have to worry about forgetting to turn off your RO or RO/DI system causing catastrophic floods.
