OK I have determined that my pool is 15,200 gallons. So when I use the chart the you gave the link to I need to add 1 quart to raise the PPM 1. You said i need to keep it at 1-3 so i fiquire when the pool is full I will dump in 3 quarts. Correct? I am guessing that I dump it in the skimmer. Then I am confused. Janet said a week for stabalzer If I understood me correctly. And Matt said right away.
