It will degrade the reinforcing steel in the concrete much faster, ditto steel pool furniture. You should have an outdoor shower for pool users to wash the salt off after they swim. I suggest researching the chlorine/bacteria issue a little more, it doesn't sound right to me. If you are trying to imitate seawater, it has about 3.5% dissolved minerals, mostly sodium chloride but also a little sodium sulfate and potassium and bromine salts, and many trace minerals. Most artificial ponds just use rock salt, but if you're a purist you can Google "sea salt" to find a source, just be sure to buy in bulk, or you will pay alot for the gourmet seasoning.-Jitney
