What is the ideal total alkalinity range for my spa?
The total alkalinity should be in the range of 90 - 150 ppm (parts per million). A spa or hot tub with low total alkalinity would require constant adjustment of the pH.
To raise total alkalinity, add sodium bicarbonate in small quantities.
To lower the total alkalinity, add acid (Dry Acid – Sodium Bisulphate) in small quantities.
