Thank you for the input. At each filter change interval (every 3
months), there's about 0.25 inch of orange sludge at the bottom of the
filter housing. There's an orange film that also coats the entire
inside of the housing as well, that I actually have to scrub off. I'm
assuming this is all of the iron, as it's the same color as the stuff
that stains the sinks. Would this be considered solids?? My main
goal was to filter this stuff from getting to the softener, and
further down to the water heater, etc. Will this orange sludge harm
the softener over time, or is the softener meant to handle this
(possibly by using the iron buster green salt)?? Just looking for
suggestions.
Thanks very much ! ...
