You start off with a Known level of salt, tested either with a salt test kit
or with one of the meters. You add a known/weighed amount of salt to your
pond, preferably somewhere where it won't hurt your fish, like in your
skimmer box or the bottom of your waterfall (if designed that way), where it
can dissolve without your fish being able to get to it. Wait a few days for
the salt to completely dissolve and get evenly distributed in the water,
then test the water again to find out what the salt content is. Then go to
this site: http://www.perigee.net/~jrjohns/volcalc.html
or http://www.akca.org/library/salt3.htm or sign up at Roark's site
http://www.click2Roark.com ; he has a very easy-to-use calculator. This
will tell you what your ACTUAL pond gallonage is. I found that the L x W x D
gives an invalid approximation unless your sides are completely vertical,
your bottom perfectly straight and level, and you're not dealing with any
curves. O'wise, you're lulled into a false sense of water: I thought I had
in excess of 1800 gals. and found out I only had 1200. That can make a big
difference in meds.

Hope this helps.

Okay, I'll bite. How do we do this?
