Administering Liquid Chlorine to Pools

One gallon of Liquid Chlorine is 4 to 6 times stronger than a typical gallon of bleach. Precautions should be taken when administering liquid chlorine to a pool. Closed shoes (such as tennis shoes, not sandals) and eye protection should always be worn. Long pants and rubber gloves are also highly recommended when adding liquid chlorine to the pool. If any liquid chlorine comes in contact with your skin, wash immediately and thoroughly. Note: Liquid chlorine should never need dilution before adding to the pool, but we will instruct customers here that in the case that dilution is needed of any chemical, never add water directly to the chemical, as this can cause a dangerous splash out of the chemical. When diluting, always add the chemical to the dilution water to prevent splash out of the chemical.

  1. Liquid chlorine is not stabilized and will burn off quickly in sunlight. Therefore, it should be administered in the evening, after the sun has set.
  2. Hold jug of liquid chlorine as far away from your body and as far into the pool as is comfortable and safe. (Do not lean over so far that you risk falling in, simply extend your arm).
  3. Pour the liquid chlorine into the pool with the jug as close to the water surface as possible in order to prevent splashing.
  4. Add the liquid chlorine to the deep end of the pool.
  5. After all of the liquid chlorine has been added, brush the walls and floor of the pool. This will help ensure any algae that are growing on the liner will be killed by the chlorine and the chlorine will be well dispersed in the water. Liquid chlorine is denser than water and will tend to settle to the bottom of the pool. Failure to brush and agitate the water may result in damage to the pool liner.
  6. Leave cover open and pump circulating overnight.
  7. In the morning, check to make sure you have a chlorine reading that is in or above the normal range of 1-3 ppm.
