Cloudy hot tub water can be caused by several things.

Natural elements like tree seed pods, dead leaves, and grass clippings can get into the water and reduce the effectiveness of the sanitizer.

Bacteria and algae growth can be another culprit, and shock can leave dead algae in the water, that can cause cloudiness.

Imbalanced water chemistry, such as pH or alkalinity changes, can cause cloudiness.

Metals in the water source can also cause cloudiness, and biofilm can coat the hot tub surfaces and plumbing and create an environment where dangerous bacteria can thrive.

An increase in bathers load is another potential cause for cloudy water. More people means more pollutants like sweat, dead cells, creams, lotions, and human waste.

How to Fix Cloudy Hot Tub Water

The first thing is to identify the cause of the problem. When you identify what is causing a cloudy hot bath tub, it will be just a matter of a few steps to get your spa to its glory days.

Start by checking the water chemistry, and if anything is amiss, adjust your water chemistry levels to their ideal range and retest your water to ensure all chemical levels are as they should be.

Check your filter if you are facing a cloudy hot bath tub problem.

Pull it out, give it a deep clean, or replace it if needed, and then run the filter for at least one hour twice daily.

Shocking your spa will be the best course of action to remove algae and maintain the chemical balance in your hot water tub. On a side note, if you are weekly shocking your spa, you won’t face such problems firsthand.

Adding a metal sequestrant can help to bind with metals and prevent them from oxidizing and discoloring your spa.

You can also use water clarifiers to remove small particles that can cause cloudiness.

Finally, flush your spa lines before draining, clean the shell, and fill with a hose filter.

Preventing Cloudy Hot Tub Water

The best way to fix cloudy spa water is to prevent it from happening in the first place.

Fill your hot tub with filtered water, stick to a regular maintenance schedule, keep your filter clean, and replace it as necessary. Maintain an appropriate level of sanitizer and use a line flush product with every water change to clear the plumbing.

Test your water before adding chemicals, and change the water every three to four months. It’s also important to make sure your bathers are taking the right precautions.

Make sure everyone showers before getting in the hot tub, and if they’re wearing swimming costumes, make sure to rinse them in warm water without any soap.

Finally, use a hot tub cover when you’re not using it to keep pollutants out of the water.

Get Your Relaxing Time Back

Cloudy hot tub water can be an annoying problem, but with the right steps, you can keep your hot tub clean and safe to use.

Check and clean the filters regularly, adjust the water chemistry levels, sock the water, and use algaecide and water clarifier to help remove tiny particles. If all else fails, you can try draining your hot tub and refilling it with fresh water.

By following the steps above, you can make sure your hot tub is crystal clear and ready for use.
