I made some water in my new home which is fed by a city well. The city takes iron out, but leaves magnesium and calcium. I run water through my water softner and then my RO
unit. I made 55 gallons and added salt and I have a heater and small circulation pump. The water has been in there a month and I noticed my thermometer, circulation pump, cords have quite a bit of sandy gritty build up on them. I can wipe it away and it seems like sand is coming off an going to the bottom, but its not really sand. My question is can I use this water or should I make another batch.
