Chlorine does not have an odor. The second is Chloramine, which is residue from chlorine already expended. Chloramines have a strong chlorine odor. The smell from
Chloramines can be eliminated by “shocking” the water. If you smell chlorine in the water, your spa is reminding you to add a shock treatment.
Question: Why can’t I fill my spa with soft water?
Answer: Soft water is essentially the same as regular water, except that most or all of the calcium has been replaced by sodium. Soft water may be corrosive to the
heater and other components. Replacement of spa components damaged by soft water is extremely expensive.
Question: I am trying to reduce the number of chemicals to which my family is exposed. Do I really need to use so many chemicals and in such large amounts?
Answer: While over-exposure to any chemical can be unhealthy, many low levels of chemicals are effective and beneficial. In the case of spa water, the chemicals
recommended in the Caldera
®
Spa Water Maintenance program are needed to protect the user from water-borne pathogens (disease-causing microbes) and to prevent
corrosion of spa components.
Question: Why isn’t water chemistry damage covered by the warranty?
Answer: The chemical levels and water quality of the water in the spa are under your direct control. With proper basic care, the spa will provide many years of hot water
relaxation. If you are unsure about any chemical or its usage in the spa, contact your Authorized Caldera Dealer or Watkins Manufacturing Corporation.
