Thanks again zeffer. Tiny yes my water is well water which is very hard. Lots of Iron in it. I had a water softener added to take the red out of my water. My toilets and tub would have a light reddish tint to it. I use salt brine tank which cycles twice a week. My water is as good as bottled water. Yes my ppm start around 200-225ppm. Is that a concern buddy?
