Alkalinity Calculator
The total alkalinity is the measurement of how alkaline your pool water is. For swimming pool water, we concern ourselves with bicarbonate alkalinity which should be maintained between 80 ppm and 120 ppm. When the total alkalinity is within range it stops the pH from bouncing up and down (sometimes called “pH Bounce”). It also helps stabilise your pool’s pH level. Water with a balanced total alkalinity level can resist, or act as a buffer, against steep and sudden changes in pH.
Note: Don’t swim in a pool after adding sodium bisulphate for at least 4-6 hours. It can cause serious burns to the skin if it comes in direct contact. Never add more than the recommended amount of sodium bisulphate to your pool at one time. It can cause surface and plumbing damage. Always add sodium bisulphate to the water slowly.
So to raise your Total Alkalinity by 10, you need to add 176 grams of Sodium Bicarbonate per 10,000 Litres.
And to reduce your Total Alkalinity by 10, you need to add 221 grams of Sodium Bisulphate per 10,000 Litres.
1000 Grams = 1 Kilogram
What is your current Total Alkalinity level: ppm
How many litres is your pool volume: litres (5283.44 US Gallons)
Your Total Alkalinity level is between 80 and 120 which is a good balance and is correct.
Your pool requires grams ( Kilogram) of Sodium Bicarbonate to raise your Total Alkalinity level to 100
Your pool requires grams ( Kilogram) of Sodium Bisulphate to lower your Total Alkalinity level to 100
