“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 

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 

problems, 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 

recommendations. 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 

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 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 

5. 

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

6. 

Soak the filter for a minimum of 24 hours.

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

8. 

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

9. 

Reinstall the filter. Do not overtighten.
