I want to be able to measure salt in my pond. How is that done?

Salt is often used as a remedy for parasites, or an "osmotic" balm for sores and ulcers in the skin of fish. The usual amount of salt applied to a body of water is three pounds of salt per one hundred US gallons of water. In tanks, they use 1 tablespoon of salt per gallon. There are precautions (Look it up!)

Later, how can you tell how much salt is in there, for example; after a water change?

There are four methods currently in use to tell about the salinity in the water.

I can, after all these years, usually estimate the salinity by taste. Enough about that.

You can make a salinity meter as described in the Book. (Look it up!)

You can buy a salt level test kit. This kit was originated by Aquarium Pharmaceuticals - and uses a couple of liquid reagents and a simple test-tube to run a test for salt levels. The number of drops of the reagent which are needed to change the color of the solution correlate to a very SPECIFIC salinity level. The AP Salinity test kit is VERY accurate. It's also simple to run. (http://www.pondrx.com) has these kits for sale.

The fourth method is with an electronic device, a Salinity Meter, manufactured under the brand name "Koi Medic" and costing well under 100$ this meter is long lived, accurate and easy to use. It comes with instructions but it is about this simple: Turn it on, dip it in the pond, read the result. They are sold at most retailers and online
