Weekly Maintenance

Because it’s such a small body of water, your spa requires consistent, frequent maintenance to keep it clear and comfortable. A simple rule of thumb: the more use it gets, the more it should be checked.



Start by testing your water for the present levels of key water conditions (always do this before adding any products): TEST WATER



Adjust the water chemistry to improve the performance of your sanitizer, help protect equipment and ensure the water looks and feels great.

Test Frequency Ideal Range
pH Twice weekly 7.2 – 7.6
Alkalinity Monthly 125 – 150ppm
Total (Calcium) Hardness Monthly or when fresh water is added 200 – 275ppm (plaster spas)
175 – 225ppm (all other surfaces)



Chlorine and bromine are the most popular sanitizers for keeping your water clean.

Test Frequency Ideal Range
Free Available Chlorine Several times weekly 3.0 – 5.0ppm
Bromine Several times weekly 2.0 – 4.0ppm (Tablets)
3.0 – 6.0ppm (Granules)



The routine addition of a clarifier will help your filter work better at keeping the water clear and inviting.


Monthly Maintenance

  • Remove buildup with a quick wipe-down of all exposed spa surfaces with a soft, non-abrasive cloth or sponge. Use a gentle cleaning solution if needed for stubborn areas.
  • Following your tub manufacturer’s instructions, take out the spa filter and spray it with a hose-end sprayer to dislodge any dirt or grime. You may need to add a chemical cleaner before rinsing to remove the oily substances and lotions that often enter the water.


Periodic Maintenance

A hot tub should be drained every 3-4 months, when a foul odor is noticed, usage has increased or when it hasn’t been used for a while.
