How to Fix Cloudy Hot Tub Water



Hazy or cloudy hot tub water is a problem that some hot tub owners face. It can stop you from wanting to enter your hot tub and can make soaking a much less relaxing experience than it should be. Like with foamy hot tub water, cloudiness can be caused by a variety of factors. But luckily, it’s very easy to fix.

Let’s take a look at some simple steps you can take to eliminate a hazy appearance from your hot tub water.

Change the amount of sanitizer you use

Hot tub users add sanitizer to their water to reduce the presence of microorganisms. If your sanitizer is low, these microorganisms could be causing the water to appear cloudy. Likewise, high
sanitizer levels can change the pH balance of the water, making it look hazy.

To maintain the proper chemical levels and keep your water clear, it’s important to use chemical test trips. After testing the chemical balance in your water, you can add the necessary chemicals to balance out your water. When your chemical levels are balanced, the water may become clear.

Clean Your Filter

If you haven’t cleaned or inspected your filter in a while, it could be the cause of your cloudy spa water.  Filters are an extremely important component in keeping your water clean, clear and
free of bacteria.

You should be doing a quick rinse of your filter with a garden hose at least every four weeks. You should also thoroughly clean your filter at least every three months to ensure that it functions efficiently. While you are cleaning your filter, install a replacement filter in your hot tub. Finally, you should replace your hot tub filter with a new one every year.

Avoid adding too many dissolved solids to the spa water

Every time you enter your hot tub, you add to the total amount of dissolved solids in the water. When body lotions, detergents, hair products and other body products accumulate in the hot tub,
they can cause hazy water and foaming.

Although we recommend that you rinse off in a shower before entering the hot tub to avoid this problem, we also recognize that this is sometimes impractical. If you don’t have the time to shower
before you soak, put your hair up and try not to apply any lotion before you enter the hot tub. Also, make sure to thoroughly rinse out all of your soap and hair products when you shower, and avoid using detergents on your bathing suit.

Refrain from using spa salts in your hot tub

Some people use spa salts to enhance their relaxation experience in hot tubs. However, excessive use of spa salts can alter the pH balance in your spa, causing it to become cloudy. This is
why we do not recommend using spa salts.

Instead, consider using spa fragrances. These spa-safe fragrances promote relaxation and contain therapeutic qualities for a luxurious spa experience. No need for spa salts that may damage your hot tub and its water.

If none of the above works, drain, clean and refill your hot tub

Sometimes, the only way to get clear hot tub water is to fill your hot tub with fresh water and continue the practices above. If you haven’t refilled your water in 4 months, it might be time to do so.

But before you drain your hot tub, use ThermoSpas Jet Cleaner to clean out the dirt, soap and bacteria hidden in your plumbing. When using our Jet Cleaner, all you have to do is add it to the water, run your pumps and jets at full power for 15 minutes, let the hot tub water sit for an hour, and then run your pumps and jets for 15 minutes again. It’s as easy as that.

Next, drain your hot tub. After your spa is empty, use ThermoSpas All Purpose Cleaner to clean the jets and shell. Then, use a hose to refill your squeaky clean hot tub with
fresh water. After this thorough cleaning, your water should remain clear and clean for a long time, as long as you follow all of the steps above.
