How to use:
• It takes about 170 grams for every 0.2 pH
  points you need to raise 10,000 gallons of 
  water. 
• In a five gallon bucket, add clean water and 
  then your measured pH Up. Slosh it around 
  a little bit to get it mixed and then pour it 
  around the perimeter of the pool.
• Make sure your pump is on during this time 
  so that the pH Up will be well-circulated 
  throughout all the water.
