What You Can Do to Clear Up Cloudy Water in Your Hot Tub

Although cloudy hot tub water can be caused by various factors, it can also be resolved with a few simple steps. Below, we will discuss what causes cloudy water in hot tubs and provide some tips on clearing it up. Let’s get started!

What Turns Hot Tub Water Cloudy?

Your hot tub water can take on different appearances, such as foggy, milky, or filled with small floating particles. Regardless of how it looks, if you want to be able to get rid of cloudy hot tub water, the first thing you need to do is figure out what’s causing it. This will help you determine the best way to clear it up. One of the most common causes is improper chemical balance. If the pH level in your hot tub is too high or too low, it can cause the water to become cloudy. Additionally, if the alkalinity or calcium hardness levels are not properly balanced, this can also lead to cloudy water.  Another common cause of cloudy hot tub water is dirty filters. If your filters are not replaced or cleaned regularly, they can become clogged with dirt and debris, which can then cause the water to have a murky appearance. Moreover, if the water in your hot tub is not properly circulated, this can also cause it to become cloudy. The circulation system helps to remove dirt and debris from the water, so if it’s not working properly, the water can become stagnant and dirty looking. Additionally, if multiple people use the hot tub, the build-up of substances such as oils, lotions or creams can create a cloudy film once they mix with chlorine. The more frequently the hot tub is used, the greater the likelihood of this occurring.

Steps You Can Take to Clear Up Cloudy Hot Tub Water

Now that you know some of the main causes of cloudy water in hot tubs, let’s take a look at some steps you can take to clear it up.

Check the water balance

If your hot tub water is cloudy, the first thing you should do is check the pH and alkalinity levels. Use a test strip or a testing kit to check the pH levels. It should be between 7.2 and 7.6, otherwise, you might need to use the right chemicals to bring it to the proper level. To learn more about which chemicals you need for your hot tub, you can get additional advice from your local hot tub dealer.

Clean or replace the filters

As we mentioned, dirty or clogged filters are often to blame for cloudy hot tub water. If you have not done so recently, clean your filters or replace them entirely. This will help to remove any dirt or debris that might be causing the water to look murky.

Make sure the water is circulating properly

Another simple step is to ensure the water in your hot tub is properly circulated. If it’s not, all the dirt and debris will settle at the bottom, resulting in cloudy water. You can use the jets to help circulate the water and remove any contaminants that might be causing the problem.

Shock the water

This is a process whereby a high-powered chlorine product is added to the water to kill any contaminants that might be causing the problem. Follow the directions on the product label carefully, and always test the water afterward to ensure it is safe to use.

Drain and refill your hot tub

If you’ve tried all of the above steps and the water is still cloudy, your best bet might be to completely drain your hot tub and start fresh. This will ensure that any contaminants causing the problem are removed from the water. Just be sure to properly clean and sanitize your hot tub before refilling it. Cloudy water can definitely dampen your hot tub experience. Luckily, there are a few simple steps you can take to clear it up. By following the tips above, you should be able to get rid of cloudy water in your hot tub and enjoy clean and sparkling water once again.
