ATO setup with x1 float sensor and dosing unit?

Hi guys,

I am looking to set up my ATO. I want to use one float sensor (in the sump) and use the 4th pump on my dosing unit. (the other 3 pumps are being used for dosing Ca/Alk/Mg)

What is the best way to set this up?

Thanks
Andrew

any update to this? Guide? pics?

Generally, the dosing pumps are not recommended for refilling water because they are only suited to dose little amounts of liquids.
They also can only run max. 15 min, then they have to stop for a while. The best would be to use a pump that you connect to
your powerbar. Select "Water1" as socket function and set Auto Top Off for the sensor, then this will work.
