The truth is, I have no intention of buying this product. As I stated earlier, I have only had to clean my unit twice since I bought it, and it is far too easy to take it apart and use a buck's worth of Muriatic Acid when it needs it.

I brought up the question as a bit of a heads up for others going to the Pool Store, and to get opinions from our Chemical Guys as to whether it would REALLLLLLLLY help reduce the calcium build up in a SWCG.
