Use this product each time you refill your spa with water.
Note: Due to the unique buffering capacity of Leisure Time pH Balance, it is not necessary to adjust the calcium hardness level in your spa.*
Use Leisure Time 4–Way Test Strip to test the pH of the water.
If the pH is between 7.0 and 7.8, go to step 3. If it is not in this range, adjust the water with Leisure Time Liquid Spa Up or Leisure Time Liquid Spa Down.
Add the entire contents of this bottle to spas containing 500 gallons of water.
*Do not use if the calcium level in the water is over 150 ppm. Leisure Time pH Balance will soften hard water and precipitate calcium, resulting in cloudy water and/or a clogged filter. If this occurs, remove the cartridge promptly and rinse any buildup completely.
Note: Not for use in spas treated with biguanide systems such as Leisure Time Free.
