while the quote from the army manual says:
9-2. Remineralization and aeration. Pure water is
a relatively reactive chemical. When air is dissolved in
extremely pure water, the resulting solution is extremely
corrosive. Water without dissolved air tastes flat and
objectionable. Water that contains very little hardness
appears to be unhealthy for drinking purposes.
Therefore, the designer of a desalination system must
consider some posttreatment options, such as
remineralization and aeration, in order to produce a
healthful, noncorrosive, pleasant-tasting water.
and a respected experienced marine hot water tank manufacturer warns of
shorter working life with watermakers.
No, I don't think we are at the bottom of the tank yet.
