@jjlanc,
To clarify my previous reply, mine is the aqc 50 gold series.
It has .50 cu ft of ion exchange resin x100.
It has a .25 brine restricter in the brine line which yields .25 gal per min brine fill. So the 11min brine fill time = about 2-3/4 gal..
Since 1 gal = about 3 lbs of salt then 2-3/4 gal would be about 8-1/4 lbs salt dose for the 11 minutes.
My system is rated at 10,900 capacity (small) so your brine fill time could vary greatly from this one.
