water - Soaking too
long - Chemicals not
balanced, excessive
ozone

solved in water pH and
total alkalinity too high

Solution
- Skim foam off using your leaf net or, drain
and refill
- Adjust pH
- Shock with a chlorine of bromine
- Raise pH with sodium bicarbonate product
- Shock with a chlorine sanitizer/shock or other
shock treatment product
- Keep recommended sanitizer residual at all
times; superchlorinate or use a non-chlorine
shock treatment - Soak for smaller intervals, such
as 15 minutes - Correct chemical imbalance
- Add a scale control product. Adjust total
alkalinity and pH levels by adding the appropriate
sodium bisulfate product; for concentrated scale
deposits - Drain spa, scrub the scale off, refill the
spa and balance the water
- Test the pH, when the sanitizer level is below
5 ppm - Replace the pH indicator dye
- Increase shock dosage; add sanitizer; shower
before entering spa - Reduce temperature
- Raise pH with sodium bicarbonate product
- Use chelating agent if metals are present
Keep proper pH level (7.2 to 7.6) - Use chelating
agent if metals are present. Maintain minimum
150-200 ppm calcium hardness - Use chelating
agent if metals are present. Maintain proper
alkalinity for type of sanitizer used.
