The system I am on is a public water system. I have had the water
retested by both the contracting company that attends to the well and
by the county water quality board. As my initial post mentions, the
community well is treated with Cl and a blend of ortho- and poly-
phosphates. The phosphate treatment is designed to bind up the iron and
manganese, as a softening treatment. The well contractor and the county
water inspector both say the treated water quality leaving the
community well easily meets NC public drinking water standards. (can't
beat City Hall)
Problem is, the polyphosphated ions break down in the hot water heater
and free the Fe and Mn and Ca back up in the house hot water supply,
with expected crusty results. Hence my search for a way to re-treat
water to remove the pre-treat ortho-poly-phosphate "softener", because
it still precipitates iron out in HW heater and manganese out in toilet
I have learned that Culligan sells a macroporous anion resin which is
supposed to remove polyphosphated iron and manganese complexes, the
whole particles, instead of splitting the phosphate off. If true,
that's fine with me, gets rid of unwanted ions and phosphate as well,
leaving the unsequestered stuff to be softened by "regular" sodium
ion-exchange water softening media. I want to get rid of that stuff,
not pass it on to the HW heater.
I am looking for non-Culligan brand alternatives to the macroporous
anion resin that a local water quality firm might use in a system that
doesn't have the breathtaking price of the Culligan $ystem ($3-4K) that
was quoted to me.
Who knows what a commercial equivalent to the Culligan macroporous
anion resin might be? I was told that particular resin was typically
used to remove dissolved organic materials such as tannic acid from
water, then it was found to be able to remove bonded complexes of
polyphosphated iron and manganese.
If Culligan's the only one with such a resin, then maybe there is some
justification to the lofty pricing.
Thanks for any help or suggestions,

BEWARE! Just before christmas SEARS changed their satisfaction
guaranteed or your money back:(
They NOW have return charges ( restocking fees) and short time limits
on returns The sears of before K Mart is gone. ask lots of questions
and get everything in writing before dealing with sears
If you ask me K Mart will kill Sears and within a few years all that
will be left is craftsman tools and Kenmore appliances sold by other
companies like Lowes...
Sears isnt a good place to shop anymore! Locally Sears stores scheduled
to be remodeled were cancelled. The $ redirected to remodel K Marts,
which actually owns sears
sad sears USED to be one of my favorite stores! Heck I bought a $800
chipper there just over a year ago, wore out the chipping blade and
found this essential part isnt available at all:( I guess stuff from
china has no parts???

Unfortunately a shelf stock softener from Sears or Home Depot or Lowe's
won't work. Those softening systems use ion exchange resins that won't
work on sequestered or phosphate-bound iron and manganese. When the
iron and manganese ions are sequestered before they get to my house,
they are not ionically available for interaction with iron filters and
traditional ion-exchange resin media. Am I wrong?
I specifically want to get rid of the polyphosphated iron and
manganese, and generic softening system media won't catch them. So I'd
be paying for the system, installation, salt, etc .... and still have
the identical original problem. Not too good...
That's why I need a special resin, either one like Culligan's white
macroporous anion media, or the Culligan product itself. I've got
special water chemistry needs that won't work with an off-the-shelf
filtering/softening system that's not designed for my specific water
If the Culligan resin is one-of-a-kind, then I'll have to buy Culligan
or have nothing. If some resin supplier has a product that can do the
same, I can probably have a local water quality vendor design a system
for a good deal less than Culligan's breathtaking quote.
OTOH, if it's a Culligan-or-nothing scenario, and they are the ONLY
ones with the magic polyphosphated iron and manganese removal media, I
might as well quit wringing my hands, write Culligan a hefty check, and
get on with it.
