“Bather Load” is the term used to describe the num-

ber of people using a spa, combined with the length 

of usage, and the frequency of usage. All these fac-

tors have a great effect on the spa water. The higher 

the bather load, the more chemicals need to be add-

ed 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  to 

4 people, 15 minutes of usage, three times a week 

at  100  degrees)  If  your  bather  load  exceeds  these 

guidelines,  and  you  experience  water  quality  prob-

lems, increase the amount of filtration first, (go to the 

next  higher  filtration  number)  then  if  water  quality 

is still not adequate, consult the advice of your Cal 

Spas dealer for additional chemical or system recom-

mendations. Be sure to give them your bather load 

information.

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. 
In addition to spraying off the filter weekly to remove surface debris, your filter should be deep cleaned pe-

riodically 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 once a month and replace it once a year or as necessary.

Remove the filter by turning it counterclockwise, unscrewing the bottom threads, then pulling it up and

out.

Place the dirty filter into a bucket of water deep enough to cover the filter. Add 8 oz of Cal Spas “Liquid 

2. 

Filter Cleaner” to the bucket of water.
Note: It is a good idea to keep a spare filter to use in the spa while the dirty filter is being deep cleaned. 

This way, you can rotate the filters and both will last longer.

Twist off the tablet tube and set it aside

3. 

Soak the filter for a minimum of 24 hours.

4. 

Spray the filter with a water hose. Spray each pleat carefully.

5. 

Put fresh bromine in the tablet tube (if you use it as a sanitizer) and twist it back on top of the filter.

6. 

Reinstall the filter. Do not overtighten.
