We had a rep from Spectra Pure at our meeting here
in Phoenix last night. On one of the orchid web sites, ( http://www.orchidgeeks.com/forum/newbie-questions/589-tap-water-and-phalaenopsis.html?highlight=chlorine ) someone
had claimed that carbon filters did not work very well on chlorine or
chloramines. My comment to him was that if that was the case, then there
should be failing RO membranes all over the place. So I brought up this
claim to the Spectra Pure rep. He said that this was wrong. That the
activated charcoal was very good at removing chlorine, including when
chloramines are used. The charcoal breaks the bond between the chlorine
and the amonia that exists in chloramines, but does not remove the amonia.
So, you can see where this leaves aquarium people. Amonia is deadly to
fish, but NOT to orchids. Cynthia, Prescott, AZ
