clean and clear

The pool.  Many gallons of shock and acid were used.  Many hours of running the filter were used.  Many thoughts of will it ever go from cesspool (the condition it was left in) to swimming pool (the current condition it is in) were thought.  Now to maintain for the weeks remaining until swimming season is done for the year.  Fun.  Not so much fun.  It's a fine balance, much like the pH.  So easy, so complex.  It makes my head swim.
