total alkalinity colour change quickly what does that mean
Total Alkalinity. The total alkalinity (TA) is a measure of how much of the alkaline substances there are in the water. In the swimming pool water, we are concerned with bicarbonate alkalinity, which should be between 80 ppm and 120 ppm.When the total alkalinity (TA) is within this range, it prevents rapid pH changes and stabilises the pH level.ote that you should only add sodium bicarbonate at the rate of 1 kg per 50,000 litres of water every 4 days. Raising the TA can therefore be quite a time-consuming, slow process. Lowering the total alkalinity is also a slow process.
