ATO

Automatic top off units keep salinity stable by replacing evaporated water without you needing to top up daily. Options here range from the Apex ATO kit to AutoAqua Smart ATO models, including nano sized versions and dual pump setups for larger systems. A good ATO paired with a reliable reservoir takes one more variable out of your water chemistry.
