Lower Hot Tub Alkalinity Tips

how to lower the alkalinity in a hot tub

High alkalinity can cause cloudy water and scaling. Here's how to reduce it for balanced and clear hot tub water.

Test and Adjust pH First

Use a test strip to check alkalinity and pH levels. Ideal alkalinity is 80-120 ppm. If high, add a pH decreaser like sodium bisulfate.

  • Follow product instructions for dosage based on tub size.
  • Circulate water for several hours after adding.
  • Retest and repeat if necessary.

Aerate to Stabilize Levels

Run jets to aerate the water, which can help balance alkalinity and pH naturally over time without additional chemicals.

Avoid adding too much chemical at once to prevent drastic swings. Regular maintenance and testing keep your hot tub safe and enjoyable.

If problems persist, consult a professional to check for underlying issues like high mineral content.
