Still able to manually dose Mag Alk and run Kalk in the Ato. But pretty soon ill be setting up the doser to Dose Cal and Alk as the demand is getting more than kalk can candle

I've been using Foz Down for about six months now as well, I just add 6-7 drops a week into my ATO water storage tank, seems to do as good a job as when I ran gfo IMO.
