I think your neighbor needs to read up more on SWGs. The only way to reduce salt in the pool is through splash out or a leak. The chemical process is pretty well documented on this. http://www.goldlinecontrols.com/Elec...orination.aspx

Also, salt readings can be influenced by water temperature or scale on the cell so it is not unusual for the readings to be off. But it would be a good idea to check for leaks anyway.
