KISS has become my motto of pool care, especially after Modding on another board that often got caught up, IMHO, on details and ignored the big picture too too often.

From my experience of working in the retail end of the business and holding a lot of peoples hands while they learned to care for their pool (usually with liquid chlorine or a SWG) I also learned that concentrating on one thing at a time and not overwhelming pool owners is the best way to teach them proper pool care.

For example, if the pH is dangerously low for a vinyl pool deal with that BEFORE you worry about getting rid of the green swamp or if the CYA is through the roof deal with with that before you start throwing out saturation index numbers at the poor pool owner! (Don't get me started on SI!)

Just my uneducated 2 cents!
