ATO has two sensors which can turn on and off a power head to automatically fill your sump with water from your reservoir
When the water level in your sump drops the automatic top off sensor will turn on the powerhead / pump (in your reservoir) on until your sump is filled back to the correct level.
Keeps your salinity constant!
The JBJ ATO automatic top off unit A.T.O is great for when you are away for an extended time.
