Q:

How do you raise the pH level of a swimming pool?

A:

Quick Answer

The pH of a swimming pool is raised by adding a pH increaser, which contains soda ash (sodium carbonate) as the active ingredient, and by testing and monitoring the alkalinity of the pool. The ideal pH level in a pool is between 7.0 to 7.6, which basically is near the same pH level as the fluid the lubricates the eyes. Low pool pH may cause several problems such as corrosion of the metal parts, erosion of the tile grout or plaster, skin and scalp irritation and a burning sensation in the eyes and nose.

The following shows how to raise the pH levels in a swimming pool.

  1. Check the pool maintenance kit
  2. Check the reagents that are being used for pool maintenance to make sure that they have not yet expired and are still suitable to use. The reagents should be effective for up to a year, but require complete replacement the following year.

  3. Testing and adding soda ash
  4. If the testing kit shows that the pH is below the recommended level, pour in soda ash following the manufacturer's instructions. Keep the ratio of soda ash to water within 2 pounds of soda ash per 10,000 liters.

  5. Adding baking soda
  6. In case the pool's pH level still drops, test the alkalinity levels of the pool after the addition of the soda ash and circulating the water. If it is below 80 ppm, add baking soda at about 1.4 pounds per 10,000 liters of water ratio. Do not add too much soda. Aerating the pool will also help raise its pH levels.
