You might want to go ahead and stock up on some bleach to finish the job--you're soon going to be at the 40-50 ppm of CYA that we recommend, and at that poing you'll need to switch to something other than the dichlor. As Watermom posted earlier in this thread, each gallon of bleach should add about 2.2 ppm of chlorine to your pool, so keep that in mind when trying to figure out how much you'll need to buy....
