Taking care of your hot tub is simple and important to keep your water clean and the hot tub running
well. Good hot tub maintenance involves regularly cleaning the filter of your hot tub and checking the
chemical levels and adding the right chemicals as needed. It is especially important to maintain the right
chemical levels in your hot tub because your hot tub equipment will corrode if the chemical levels are
too high and bacteria can take over if the chemical levels are too low. Overall, regular attention to your
hot tub maintenance will keep your hot tub water sparkling and inviting for all bathers
1 – Test Strips
Use test strips to check the chemical and mineral levels in your hot tub. You should be checking and adjusting
the chemical levels in your hot tub 1-2 times a week and some test strips provide 6-in-1 readings,
including total alkalinity, calcium hardness, chlorine, pH, bromine, and total hardness. Put these strips in
your hot tub for as little as 15 seconds and then view the results.
2 – One chemical at a time
Add one chemical to your spa at a time. When adjusting hot tub chemical levels, add one chemical to the
water, and then wait a full two hours before adding another chemical. This will allow the chemicals to disperse
naturally and will help to maximize their effectiveness. Waiting also minimizes the risk of a chemical
reactions between the additives that can cause problems.
- Keep your spa cover off for at least 15 minutes after you have added your chemicals.
- Keep your spa water running when you add the chemicals. This is important because you
want the jets to mix the chemicals in the water well.
3 – Check total alkalinity
Check total alkalinity first. Use your test strips- a well balanced spa should be between 80-120 PPM in
total alkalinity. It is important to maintain your alkalinity first because it affects your pH.
4 – Use chlorine or bromine to sanitize
Use chlorine or bromine to sanitize your hot tub. Make sure to use test strips to maintain the correct
chemical levels. Chlorine is the old standard for sanitizing your spa; however, it has been largely replaced
by bromine because bromine is less harsh and has a less potent smell.
5 – Check for calcium hardness
Check for calcium hardness. The best way to keep the calcium hardness in your spa in check is to use soft
water in your spa. If your spa has too much calcium hardness, it will cause scales to form in your spa
6 – Check the pH levels
Check the pH levels last. Your pH should stay between 7.2-7.8. If the pH is off, first work to stabilize the
total alkalinity. Then make sure you have added the proper amounts of chlorine/bromine to your hot tub.
And then if the pH is still off, add a pH balance product to your hot tub pH level.
- Your pH levels may be adjusted if: the sanitizer you use is not working well, your spa has
cloudy water, scales have developed on your filter, or the water is causing skin and eye irritations.
7 – Shock your hot tub
Use chlorine or bromine shock treatments, depending on which sanitizer you are
using in your water, to shock your water once a week as well especially when there have been a lot of
bathers using the hot tub.
8 – Shower before use
Shower before using the tub. Rinse out your hair and body care products before you get in the hot tub.
If your hot tub water is murky or there is foam forming in your spa, it could be due to lotions and body
products people wear into the tub.
Clean the filter every week. DON’T RUN THE HOT TUB WITH NO FILTER. To unclog and clean your hot tub
filter, take the cartridge out of the filter. Using a hose, run water over each pleat in the cartridge and clean
any dirt and foreign matter out of the filter. Make sure to let the cleaned filter air dry completely before
putting it back in your filter.
- Replace the spa filter when it has become damaged or has stopped working. You’ll know
this is the case when the filter quickly become dirty again after you have cleaned it.
