Filtration
The filter is the part of your spa that removes the debris from the water. Even though Cal Spas uses the
advanced Bio Clean filter cartridge that protects itself from bacterial growth, the filter still needs to be cleaned
on a regular basis to maximize your spa’s filtering performance and heating efficiency.
In addition to spraying off the filter weekly to remove surface debris, your filter should be deep cleaned
periodically to dissolve scale and other contaminants that get lodged deep within the filter fibers and impede the
filtration process. Even if the filter looks clean, the contaminants 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.
Filter Cleaning
• Place the dirty filter into a bucket of water deep enough to cover the filter. Add 8oz of Cal Spas “Liquid
Filter Cleaner” to the bucket of water.
• Note: It is a good idea to keep a spare filter to be deep cleaned while the regular filter is in the spa. This
way, you can rotate the filters and both will last longer.
• Soak the filter for a minimum of 24 hours.
• Remove the filter and spray clean with a water hose. Spray each pleat carefully.
• Allow filter to dry completely (a minimum of 2 days drying time is recommended).
• Reinstall filter as described in the “Clear Water Plan”.
Filtration Cycles
The filtration cycle of your spa is the process that allows the water to flow through the filter. Your spa will filter
automatically twice each day. The factory set default time for filtration is usually enough for normal use,
however heavy bather load or frequent use may require longer filtration times or more frequent filtration cycles
to keep the spa water clean. Consult your Owner’s Manual for setting your spa’s filtration times.
Bather Load
“Bather Load” is the term used to describe the number of people using a spa, combined with the length of
usage, and the frequency of usage. All these factors have a great effect on the spa water. The higher the bather
load, the more chemicals need to be added and a longer filtration time will be needed.
All versions of the Cal Spas “Clear Water Plan” are designed for spas with average bather load. (3-4 people, 15
minutes of usage, 3 times a week at 100 degrees) If your bather load exceeds these guidelines, and you
experience water quality problems, increase the amount of filtration first, (go to the next higher filtration
number) then if water quality is still not adequate, consult the advise of your Cal Spas dealer for additional
chemical or system recommendations. Be sure to give them your bather load information.
