roughly...
1/2 cup salt in 1 gallon = 3%, the concentration for a dip.
1/2 cup in 10 gallons = 0.3%
1/2 cup in 30 gallons = 0.1%
10 x 1/2 cup or 5 cups of the course rock salt used in water softeners will
give you
about 0.1%

The above is something I saved from RP that came in handy today, so I
thought I'd put it up in RPM.

A couple koi club members went to the Portland show and picked me up a
couple of wakins. I put them in with a small one (or 2*) of mine, and then
my son points out my small one has something wrong with its mouth.s So I
decided to salt the little pond they're quarantined in. Thus... the C&P
above came in handy (thanks Ingrid). ~ jan

*There were 2 babies in there, but I've only seen one at a time for the
last several days... probably not the best place to put new fish... but oh
well. The filter is in good shape and it was ready to go.
