Chemical Maintenance

Chemicals & Additives

Water chemistry balance is extremely important in maintaining good water quality and the preservation of spa equipment. It is a simple task to maintain your spa chemistry in balance. It must be done on a regular basis. The 2 parameters that have to be maintained are the pH and chlorine content.

pH BALANCE: pH is a measure of water acidity. On a scale of 0 to 14, 7.6 is the ideal point of balance. A measure below 7.6 indicates that spa water is more acid. Such a condition results in corrosion to spa equipment metal components. Above 7.6 means that spa water is more alkaline. This causes salt deposits, and scaling in the equipment and in the spa. Both conditions are detrimental and can cause damage.

CHLORINE / BROMINE:Of One of these sanitzers must be used to remove bacteria and other organic matter from the spa. Low sanitizer causes water to turn green and unhealthful. A high level makes water smell pungent, irritate the eyes and the skin and can cause damage to the metal components of the spa equipment.

Do not use chlorine other than what is designated for spa use. Specifically do not use chlorine intended for pool use.

The booklet or video tape that came with your spa’s chemical kit contains detailed procedures for maintaining spa chemistry. Your dealer stocks a variety of chemicals to maintain spa chemistry and can help you in the selection of the right chemicals and their methods of application.

A number of other additives are available to enhance spa usage. These include additives to remove dissolved metals, reduce foaming and sudsing, remove body oils, some make the water feel and smell better. Your dealer can help you select the right additives .

Chlorine vs Bromine: Both these sanitizers if properly applied will maintain a sanitary spa. There are pros and cons on both sides, but the choice is up to the user. Please note these sanitizers are caustic, excessive dissolved amounts of which will cause damage to the spa equipment. It is therefore necessary to maintain the proper balance by periodic measurement of sanitizer content.

Ozone & Ozone Generators

If your spa is equipped with an ozonator, you will have to set the spa to filter for at least 6 hours per day, preferably in 2 or 3 time periods. Please note that ozonators and chemical treatment are complimentary. Ozonators cannot totally eliminate the need of chemicals such as chlorine or bromine.

Ozone is a bactericide. The active component in an ozonator is the ultraviolet light bulb. When power is applied to the bulb, ozone is generated. A tube links the ozone compartment with one or more jets. When these jets are activated, water movement within the jet creates a venturi action that draws the ozone out of the ozone compartment, mixes it with the moving water purifying the water in the process.

The light bulb has a limited service life. Its production of ozone is degraded with use. Consult the manual of the ozonator’s manufacturer to determine when the bulb should be replaced.

Ozone is harmful. Do not inhale ozone for an extended period of time.

Ultraviolet rays are harmful to human eyesight. Do not look directly at a burning ozone bulb.

Chemical Safety Tips

Read all labels and instructions carefully prior to use.

Never mix or combine one chemical with another.

When mixing always add chemicals to water, not water to chemicals.

Store chemicals in a cool and dry place.

Store chemicals out of the reach of children.

When not in use keep chemical containers tightly closed.

Never inhale chemicals or their fumes.

Do not allow chemicals in contact with eyes, nose or mouth.

Wash your hands thoroughly after handling chemicals.

Use chemicals especially formulated for hot tubs and spas (not pools).

Never drain chemically treated water on plants, lawns or in streams or lakes.

Test your spa chemical levels at least once a week.

Maintain the pH level at 7.2 to 7.4.

Maintain a sanitizer level of 3.0 to 5.0
