Cloudy water in your hot tub is a sign that something’s wrong. It could be due to the presence of particles or ineffective chemicals. Read on to know the causes and solutions to clear cloudy hot tub water.
5 Causes of Cloudy Hot Tub Water
Below are some common causes of cloudy water:
1. Alkaline

Alkaline is a common cause of cloudy hot tub water. High levels of alkaline can contribute to cloudy water, making it appear milky or foamy

To prevent cloudy hot tub water, it is important for hot tub owners to regularly test their spa water and use the right hot tub chemicals to maintain water balance.
2. Not Enough Sanitizer

Cloudiness can happen after increased hot tub use. Lack of chlorine and bromine can make the water cloudy.
This can cause the water to become cloudy or milky, making it difficult to see if the water is clean.
To fix this issue, you can refill your hot tub with fresh water and add the necessary water chemicals.
3. Hot Tub Filters

Let’s not forget about the Hot tub filters. They work hard to keep dirt and debris out of your water. But if they’re clogged up and not cleaned regularly, they can’t do their job, leading to cloudy water.
4. Care Products

Lotions, oils, and soaps on your skin can affect your hot tub’s water clarity. Using these products before entering the hot tub can cause cloudy water and foamy water, leading to cloudy or milky water in your tub.
5. pH Levels in Your Hot Tub

Maintaining the right pH level in your hot tub is essential for keeping the water balanced and comfortable for you, as well as ensuring the proper functioning of the hot tub equipment. A pH level of 7 is ideal, as it indicates that the water is neither too acidic nor too basic.

How to Fix Cloudy Hot Tub Water?
Here’s how you can fix cloudy hot tub water:
Test Your Water

Test your hot tub water regularly to ensure it stays clean and clear. If your hot tub water is cloudy, you may need to drain and refill the tub water. Using a non-chlorine shock treatment can help remove particles from the water and keep your water clear and clean.
Check the Water Surface

One of the best ways to fix cloudy and foamy water is to check the surface of your water with a hot tub test kit that measures substances in your water. This will help determine what is causing the cloudy water and how to fix it to keep your hot tub water clean and clear.
Adjust Water Chemistry

If your tests show that the water is off-balance, don’t worry! You can fix it by adding chemicals specifically made for hot tubs. To raise or lower pH, you would use products like pH increasers or decreasers.
For alkalinity, you might add an alkalinity booster. Always follow the instructions on the product labels, and add chemicals slowly, giving them time to mix and work.
Maintaining Perfect Water Balance

Regular testing and tweaking will keep your hot tub’s water in the sweet spot. This means testing a couple of times a week and after heavy use or big weather changes.
By staying on top of the water conditions, you’ll ensure a safe and enjoyable experience for everyone who takes a dip.

Shower Before You Soak

Showering before using a hot tub is important to keep the water clean and clear.
Substances on our skin can change the water’s chemistry, and a quick shower can rinse off most of these impurities.
Showering before getting in also shows respect for others who share the hot tub. Keep a towel and soap next to the hot tub to make it a habit.
