AutoAqua Smart ATO RO

AutoAqua Smart ATO RO

Overview

The AutoAqua Smart ATO RO is an automatic top-off controller designed specifically for filling your RO/RODI reservoir directly from an RO system—automating the refill of your storage container rather than the aquarium. Using dual optical sensors and a float valve backup, it refills your reservoir when the water level drops, then automatically shuts off the RO/DI system when it reaches the top, preventing floods and reducing TDS creep.

This system ensures you always have a full supply of purified RO/DI water for auto top-off systems or water changes while extending the life of your DI resin by minimizing short, frequent RO cycles.
