·      Since salt water pools produce chlorine, the sanitizing effectiveness of the system is affected by sunlight, rainfall, bather load, phosphate levels, temperature and calcium buildup.  Changes in any of these conditions can lead to an algae bloom and require additional ‘shocking’ of the water.

·      Backwashing salt water pools can sterilize soil and kill plants.  Many municipalities prohibit salt water backwashing in the U.S. and Australia (where salt water systems originate from).
