Jan,
If you do not mind I would like to add this concept to the HTH page on
water changes. Maybe start a pond specific section.

jan, the "divided by 13" comes from your beginning figure of .13? Kewl!

I did a water change today and thought I'd do a salt check before and
after. Before the change I had a salt level of .13%, after I had .11%.
Bascially doing a little more than a 15% water change out. (13 - 11 = 2, 2
divided by 13 equals .154 or 15.4%) Surprised me. Here I though I was

doing

between 20-25%.

So for those of us who don't have perfectly straight walled, flat bottom
ponds who could calculate their water change % in feet (or inches) i.e., 4
ft of pond, drain down 1' equals a 25% change out. Here is another way to
use your salt test measurements. ;o) ~ jan
