One way to add soda ash to a swimming pool would be to create a slurry with it first in a bucket of pool water, and then pour the mixture slowly into the pool. Alternatively, the soda ash can also be poured along the edge of the deep end of the pool. The soda ash must not be poured in one place as it can cloud up the swimming pool.
Soda ash, or sodium carbonate, is one of the basic pool additives for maintaining the pH balance between the acidity and alkalinity of the pool. Soda ash is added into a swimming pool whenever its pH or alkalinity level needs to be raised.
Pool experts recommend that the pH levels in a pool must be kept between 7.4 and 7.6 pH. A lower pH means that the pool is acidic. A pool with too much acidity or has a low pH is susceptible to pool problems such as staining from corroded metal parts; eroded plaster or grouting; and damaged pool accessories. Any person who enters a pool in this condition can suffer from burning eyes and nose, itchy scalp and dry skin.
Pools with a high pH or alkalinity may encounter problems such as calcium buildup, cloudy water and algae growth. A person can still suffer from burning eyes and nose in a high pH pool. To lower pH levels, chemical additives such as muriatic acid and sodium bisulfate are added into the pool.
