Water Chemistry Maintenance
Action Frequency
1. Test and Balance Alkalinity: Bi-Weekly
There are three products needed to test and balance alkalinity:
• Test Strip: provides a reading on the alkalinity level;
• pH/Alkalinity Up: raises the alkalinity level; and
• pH/Alkalinity Down: lowers the alkalinity level
The acceptable alkalinity level must range between 80-120 ppm (parts per million).
Follow the Adjust Alkalinity/pH.
2. Test and Balance pH Bi-Weekly
There are three products needed to test and balance pH:
• Test Strips: tests the pH level;
• pH/Alkalinity Up: raises the pH level; and
• pH/Alkalinity Down: lowers the pH level
The acceptable pH level must range between 7.2 – 7.8. Do not enter your spa if
the pH level is out of range, or you risk the possibility of skin and eye irritation.
3. Test Total Dissolved Solids (TDS) Monthly
Increases in Total Dissolved Solids will cause your sanitizer to become ineffective.
Once Total dissolved solids have reached a level of 3000 your water should be changed.
• Use test strips to check level of Total dissolved solids.
• If the reading is 3,000 ppm or less, the spa requires no maintenance.
4. Treatment of Minerals and Metals Weekly
Control any staining or discoloring of the water caused by minerals. Using these
chemicals help prevent scale from forming on the shell’s surface and/or any corrosion
occurring to the heater element.
• Have your water tested for mineral content, send a water sample
to ThermoSpas’ Customer Care Department for a free analysis.
For weekly water maintenance add 1 oz. of Stain & Scale.
5. Treatment of Oils and Organics Weekly
Bathers bring lotions, skin, hair and other organics into spas. Using a natural enzyme that
breaks down and devours oils and other organics that sanitizers cannot destroy is essential
to maintaining clear water. Natural & Clear immediately breaks down the organics by converting
them into a gas before they can interfere with the sanitizers’ performance. Because it dissolves
the organics as opposed to coagulating the organics like most other clarifiers used by competitors,
Natural & Clear helps rid the acrylic shell of the unsightly “scum line” above the water’s surface.
• For weekly water maintenance add 1/2 oz. of Natural & Clear.
6. Excessive Foaming As Required
To correct foaming caused by soap or other residues, use ThermoSpas Foam Away. Make
certain to shake container and disperse only ONE capful where foaming is occurring while
water is circulating. Wait 30 minutes and repeat treatment if foaming continues. It is
recommended to clean your filter within 24 hours of using Foam Away. Using too much
Foam Away will cloud your water, taking as much as 24 hours to dissipate. Add only 1 capful
at a time and please be patient.
7. Cleaning Biofilm in your spa plumbing lines Drain and Refill
Over time biofilm can accumulate in your spas plumbing lines. Using a Jet Line cleaner
at least twice a year is recommended to ensure excessive growth of bacteria does not
cause increased use of sanitizers.

4. Scheduled Maintenance
• Clean the shell above the water line with ThermoSpas All Purpose Cleaner once a week.
• All Purpose Cleaner will not alter the water chemistry, or scratch the acrylic shell.
• Thermospas does not recommend the use of household cleaners on the spa shell. Most will
alter the water chemistry and some contain abrasives that will scratch and dull the spa shell.
• The Scum Mitt offered by ThermoSpas is ideal for use with the All Purpose Cleaner.
• Clean the spa filter(s) at least every 1-3 weeks depending upon usage.
• Follow the cleaning process outlined in this manual. Additional information relating to filter
maintenance may be found in the Special Operation Instructions that came with your spa.
• If the spa is used heavily the filters should be cleaned at more frequent intervals.
• Having a second set of filters on hand is strongly recommended as they greatly reduce the
down time the spa requires for filter maintenance.
• Drain and refill the spa every 3 to 4 months (Spas with ThermOzone 6 to 12 months depending on usage).
• Follow the drain and refill procedures in this manual.
• Each time the spa is drained and refilled the lines should be flushed and cleaned. Follow the
procedure outlined in this manual.
• It is recommended the entire shell surface be cleaned and protected each time the spa is
drained and refilled. Use All Purpose Cleaner and ThermoGloss as outlined in the procedure
in this manual.
• The filter(s) should be cleaned with each drain and refill. See this manual and the Special
Operating Instructions that came with your spa.
• Spas that are used heavily will require more frequent drain and refill cycles.
• Conditioning the Cover Monthly.
• The cover should be thoroughly cleaned and conditioned once a month using ThermoSpas
Cover Conditioner.
• Cleaning and Protecting the Cabinet.
• Cabinets constructed of ThermoBoard require hosing and wiping down once or twice a year.

times a year.
