Amount of Soda Ash needed to raise pH to 7.4
Actual pH        25,000 gallons         50,000 gallons          100,000 gallons
6.6                  3 3/4 lbs                       7 1/2 lbs                 15 lbs
6.8                   3 lbs                             6 lbs                      12 lbs
7.0                 2 1/4 lbs                       4 3/4 lbs                  8.5 lbs
7.2                  2 lbs                             3 1/4 lbs                 6.5 lbs
To Add: Fill a clean bucket with water. Carefully add soda ash. For best results, dilute soda
ash as much as possible with water. Stir until dissolved with a clean rod. Pour solution down

Warning: Do not add more than 1 pound of soda ash per 10,000 gallons of water at a time
as it may cause the pool to cloud ("milky" consistency). Also, if your alkalinity is over 120
ppm, the addition of soda ash may also cause your water to cloud.

Amount of Muriatic Acid needed to lower pH to 7.6

Actual pH         25,000 gallons         50,000 gallons       100,000 gallons
8.4                     3/4 gallon                 1 1/2 gallon             3 gallons
8.2                     1/2 gallon                 1 gallon                   2 gallons
8.0                    1 1/2 quarts               3 quarts                  1 1/2 gallons
7.8                     3 1/4 cups                 1 1/2 quarts          3 quarts
Muriatic Acid to water. Carefully pour down side of pool distributing solution over as large
an area as possible. Close the pool for at least 30 minutes before allowing swimmers to
re-enter.

Warning: Never mix acid with any other chemicals. If splashed in eye, immediately irrigate
with water for at least 15 minutes with large amounts of water - Call 911. If splashed on
skin, wash with large amounts of water for at least 30 seconds.

1 quart = 32 ounces
1 cup = 8 ounces
