How to Clear Up a Cloudy Hot Tub

Lisa Wampler

Cloudy water in your hot tub, pool, spa or Jacuzzi is an indication that your water has suspended particles floating in it. In general, this means poor filtration and/or poor water balance. When you notice cloudy water, there are several steps you can take to rectify the situation.

Hot tubs are great until the water turns cloudy.

A visit to your local pool store or hot tub supply retailer will be in order but with a little troubleshooting, you can resolve your cloudy water issue.

  1. Inspect the filters in your hot tub for clogging or tears. If the filter is clogged, it will restrict the flow of water and stop removing particles. If the filter is torn, it will allow water to flow freely and not remove any particles. This can cause you water to turn cloudy. Replace any defective filters with new filters.

  2. Run your hot tub on a regular basis. If you do not have your hot tub on, the water does not flow through the filters. The water sits in the hot tub and starts to stagnate. If you do not use a lot of chemicals to keep the water fresh, the stagnating water will start to cloud. Running the hot tub on a regular basis will ensure the water does not stagnate.

  3. Treat the water with “water shock.” You can get water shock from your pool or hot tub supplier. To total dosage depends on the size of our hot tub and the severity of the situation. Water shock dissolved the particles in the water. It is important that you follow the directions written on the bottle of shock to ensure you run the hot tub for the appropriate amount of time after using the water shock. This will ensure your safety.

  4. Drain the water and replace it with fresh water. Sometimes, the particulates in the water are too dense for any chemicals or filters to remove. If this is the case, draining and refilling is the best option. This option is best done in conjunction with replacing the filters.
