Understanding Water Balance in a Swimming Pool

A balanced swimming pool must always be attained and this means maintaining water balance, and that’s why it is important first to know the reasons why a water balance is required for maintaining a safe pool.

A good water balance in a swimming pool must have a pH reading that falls in the range of 7.4 to 7.6 to attain a safe water condition where there are no presences of germs and bacteria; therefore, if your pool is either using a salt-based pool producing chlorine or a chlorine-based tablet pool, then the pH of the water needs to be corrected for the chlorine sanitizer to function effectively. The pH reading of a pool water indicates whether the water is acidic or alkaline, such that a reading of 0 to 7.0 reflects an acidic water level and a pH reading from 8.0 to 14.0 means the pool water is basic or alkaline. Because the ideal pH reading of 7.4 to 7.6 must be maintained in a pool water, it means that the right water balance is slightly alkaline or slightly neutral.

The indication of allow pH reading (below 7.4) allows for chlorine to dissolve quicker, which means the pool water when maintained with chlorine or bleach will make the water more acidic, causing skin and eye irritation, and corrode the pool liner, ladders, hand rail and pump, while a high ph reading (above 7.6) males the pool water to be more alkaline, which makes the chlorine or bleach used for disinfecting pool ineffective, which results into bacterial and germ presence in the pool, as well as introducing corrosion to the pool accessories. A balanced water in a swimming pool must have an alkaline reading of100 ppm (parts per million), therefore, aside from the pH reading, there is another way to determine the water balance in a pool using a device that measures the alkalinity reading.

Aside from the right pH reading and correct alkaline ppm, to have a balanced water in the pool is to have the ideal calcium reading of 300 ppm; if the calcium reading is below 300 ppm, this means there is less calcium and this can cause erosion of the pool plaster, while too much calcium, above 300 ppm, could make the pool water cloudy such that scaling and stains may build up.

Since there is need to disinfect the pool using chlorine or bleach for maintaining a safe pool, it is important to use a stabilizer to make the chlorine stay longer just enough to make disinfection work.

All water contains dissolved minerals that remain in the pool and become concentrated when the water evaporates, and when this happens, it is hard for chemical additives, that are applied to the pool for maintenance, become effective, therefore, there is need to either drain some water or add fresh water.
