Keep Up with Water Chemistry

Keeping Up with Water Chemistry

The secret of hot tub care and cleaner water is to test the water! Use these results and make small adjustments to pH, alkalinity, calcium hardness and sanitizer levels regularly. This means testing the spa water 2–4 times per week and adjusting levels as needed to keep the water balanced within the proper ranges:

• • Chlorine: 1.0–3.0 ppm
  • Bromine: 2.0–4.0 ppm
  • pH: 7.4–7.6
  • Total Alkalinity: 80–120 ppm
  • Calcium Hardness: 150–250 ppm

Keeping a water test log is a good idea to track your test results and make notes on adjustments. In many cases, you’ll start to notice patterns in water chemistry, especially with pH and sanitizer levels.

Tap water is good spa water in most areas. But in some areas (you know where you are), you may run into water quality issues. Soft or hard water, high alkalinity, pH imbalance, and high levels of chloramines, metals or minerals can all negatively impact water balance in your hot tub. Use a test kit to sample your tap water directly from the source or after a drain and refill. This will help you gauge the suitability of your tap water for use in the spa. Using a spa pre-filter removes metals, odors and the finest silt from your spa fill water.
