membership updated; Pool Chart data added to signature.

There is no 'right' settings on tab feeders -- the amount of chlorine added depends on your pump and piping arrangement, and is highly variable from pool to pool.

Also, while it's possible to maintain a pool without shocking, most people aren't careful enough with their levels to do so successfully. In fact, with your CYA levels (CYA=100+ ppm) it's not possible to maintain good results with regular pool information, or without a K2006. Read the Best Guess page, linked in my blue signature bar, for a fuller explanation.
