  • Check the total alkalinity using a test kit. The ideal recommended alkalinity level is 80 to 120 ppm when chlorine is used as a sanitizer, and 100 to 150 ppm when using bromine.
  • To increase total alkalinity by 10 ppm, dissolve 16 g per 1,000 L of spa water in a bucket of water. Add the solution to the spa water.
  • Check alkalinity levels regularly and readjust as needed.

FAQ


  • pH stability: alkalinity “buffers” the pH. Too low = pH roller coaster; too high = pH difficult to lower.
  • Problem prevention: Correct alkalinity limits corrosion, turbidity and scaling.

To adjust the alkalinity of a spa, you must first measure the current level using a test kit or test strips. If the alkalinity is too low, add an alkalinity booster; if it is too high, use an Alka Minus product. The goal is to achieve a value between 100 and 150 ppm, which stabilizes the pH and improves the effectiveness of chlorine or bromine. Proper alkalinity makes the water more comfortable, reduces pH fluctuations, and protects spa components from corrosion and scale buildup.

  • Then aerate (jets/bubbles) to raise the pH without raising the total alkalinity too much.
  • Re-test and repeat in stages.
  • Symptoms of total alkalinity outside the range:
  • Too low (<100 ppm) → unstable pH, “aggressive” water, risk of corrosion, irritations.
  • Too high (>150 ppm) → pH difficult to lower, cloudy water, limescale deposits.
  • Tip: Adjust only one product at a time, follow the label, and respect the balancing order: total alkalinity → pH → hardness.

Total alkalinity is the buffering capacity of water: it stabilizes pH and prevents sudden changes. The target in spas is 100–150 ppm. Below this, pH becomes unstable and the water can become aggressive to surfaces and metals; above this, pH becomes difficult to lower and cloudiness/scale may appear.



To increase the alkalinity of a spa, you need to use a product designed to raise it, often called “Alka+”, “alkalinity booster”, or “alkalinity plus”. Add the product directly to the spa water, according to the recommended dosage based on the spa's volume. The ideal alkalinity is between 0 and 150 ppm and acts as a buffer to stabilize the pH. When the alkalinity is too low, the pH becomes unstable and fluctuates constantly. After adding the product, circulate the water for 20 to 30 minutes, then retest to confirm the reading.
