Shocking the Water

In addition to using a chemical sanitizer, you will periodically need to shock the water. Shocking helps refresh the water by breaking down organic waste contaminants which cause odor and cloudy water. After treatment, water quality and clarity is often completely restored.

The two types of shock are sodium dichlor and potassium monopersulfate (MPS). You can use either type of shock regardless of which sanitizer you use. Even if you use bromine, you can use a chlorinated shock if you wish -- in fact, you may find a chlorinated shock is more effective than dichlor or MPS alone.

If irritating chloramines are present, shocking also converts them back to active chlorine. If you use bromine sanitizer, shocking activates the bromide ion (which by itself has no disinfecting capability) which becomes hypobromous acid in water, a good sanitizer.

Add one ounce of oxidizer shock once a week, after heavy bather loads, or if water has a strong odor.

Spa must be running with all of the jets on high for 30 minutes with the cover open. If necessary, repeat shock in

30 minute intervals.

3. Filtration

The filter is the part of your spa that removes the debris from the water and needs to be cleaned on a regular basis to maximize your spa’s filtering performance and heating efficiency.

It is extremely important that you never run the spa without a filter. There is a possibility that debris may be sucked into the plumbing through the filter well.

Cleaning the Filter

In addition to spraying off the filter weekly to remove surface debris, your filter should be deep cleaned periodically to dissolve scale and particles that get lodged deep within the filter fibers and impede the filtration process. Even if the filter looks clean, scale and particles can clog the fibers and prevent water from flowing through the filter resulting in the most common spa problem—no heat, caused by a dirty filter.

We recommend you clean your filter at least once a month, possibly every two weeks depending on how frequently you use your spa, and replace it once a year or as necessary. See page 37 for instructions on removing and cleaning the filter.
