Some manufactures make hard water nutes that would help. if you can't get an R/O filter and water is too much, you could try mixing half and half. That would bring you ppm's down to 350.

It's not just the flouride or the chlorine. They are using chloromine. This is a solid chlorine that does not eveporate. This is to keep it clean in very long runs of water pipes.

I wonder what the health problems are for the people drinking this water. Like clogging veins and hard mineral build ups in your liver and kidney's.

Hope you can get a filter soon.
