Do it to the water before you make the CS.  Be aware that the carbon fines
in some fresh carbon filters will increase conductivity significantly.

Subject: CS filtered through carbon, cotton or resin bed?

Dear Marshall, Ivan & other members


Would there be any reaction in a CS solution that is filtered through a
carbon filter, cotton filter or resin bed?

The idea would be to clean out any oxides or other impurities which may have
formed.

To put the question differently: What would be the best filter to use for
this purpose?

All feedback will be much appreciated.

Many thanks

Steve
