Dissipating
Too Rapidly
Usual Cause
- Build up of body oils,
lotion and chemicals
resulting from soap or
detergent
- pH Imbalance
- Low free chlorine or
bromine
- Low pH - Insufficient
free available chlorine
- Unsanitary/polluted
water - Soaking too
long - Chemicals not
balanced, excessive
ozone
- Too much calcium dis-
solved in water pH and
total alkalinity too high
- Sanitizer level too high
- Old pH indicator dye
- Excessive organics in
water
- Temperature too high
- Low pH
- Low pH corrodion of
metal fixtures
- Low calcium hardness
- Low total alkalinity
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.
