At least the forum is titled correctly. Why not change use of the acronym to be more descriptive? Try to use SWCG instead of SWG when discussing it. In an undocumented survey of pool owners, over half (36.5%) did not realize that a salt water pool was based on chlorine sanitation. They thought it was something else. In an unrelated survey, over 66.3% of statistics were found to be made up.
