The ideal pH range of swimming pool water is between 7.4 and 7.6. When the pH value is lower than the measured value of 7.4, the walls and bottom of the swimming pool will begin to dissolve, causing algae to grow in the swimming pool water, which can be increased by adding edible sodium bicarbonate Alkalinity in the pool.
There are many reasons for the decrease in swimming pool alkalinity, including: a large amount of rainwater enters the swimming pool, which causes the water to be diluted, acid rain can cause alkalinity and pH to drop, and sweat or even urine can lead to a decrease in alkalinity.
You may need to increase the alkalinity when testing swimming pool water below 80 PPM with a pH sensor. Sodium bicarbonate is very safe, so you don't need to wear any protective equipment during use.
