Mange in Fox and Coyote. Sarcoptic mange is probably the biggest killer of red foxes and coyotes in New Jersey. It is a highly contagious disease and can be easily spread. It is caused by an infestation of Sarcoptes scabiei canis, a burrowing mite, causing intense itching from an allergic reaction to the mite and resulting in hair loss.
Chemically, the difference between the two is that hard water contains calcium and magnesium ions, while soft water does not. Soft water is easier to lather with than hard water is. Continue Reading.
The most common treatment applied to hard water is ion exchange, aka water softening. In a water softener, the bad ions (minerals) are taken out of the water while softer ions are returned to it. This process is an almost equal exchange: there are still as many minerals in the water after water softening as before, but the water is now softer. It will, of course, still cause some scale buildup, as the soft dissolved minerals can still precipitate out.
