Help! I have Cloudy Hot Tub Water

Cloudy Hot TubIs your hot tub water cloudy? Even after you recently drained & refilled your spa?

Cloudy Hot Tub Water is usually caused by two things:

  1. Water that is out of balance
  2. Bacteria in the water.

Try these steps for cloudy hot tub water:

  • Test your water balance (Test in this order: Total Alkalinity, pH and Calcium Hardness) Adjust as necessary
  • Test the sanitizer level in your hot tub (This may be Chlorine, Bromine or Baqua Sanitizer depending on the system you are using) and make sure it is in the recommended range. If the sanitizer level is low, increase until it is in the recommended range & wait 24 hours to see if the hot tub cloudiness disappears.
  • If your water is still cloudy, add 2 TBSP of oxidizer (Only for Salt/Chlorine/Bromine water care systems) & run the jets with your cover open for 20 minutes. Wait 24 hours to see if the water clears up.
  • If your water is still cloudy it is most likely caused by hair gel, lotion, make-up, sunscreen etc. that is transferred off your body & into the water. Add a few squirts of a Water Clarifying product to the water. Run the tub with all the jets on as often as possible. Wait 24 hours and the water should be clear.

If your hot tub continues to be cloudy, we recommend having your water tested professionally. If you’re in the Philadelphia or South Jersey area, contact one of our 3 hot Tub showrooms for a water test!

    Only been using my jacuzzi outdoor tub one week and it’s already cloudy.i never take the lid off except to get in it. Chemicals are all correct. Could that be a cause? Should I leave this off more frequently. I’m trying to keep the 104 degree temp efficiently.

    • Deborah,
      Usually you’re using your hot tub SO much in the first week since it’s new that it can be a bit cloudier than normal. I’m not sure what chemicals you are using, but if it’s chlorine, you could double the amount you’re supposed to put in the water until it clears up. Hope that helps!

        Thank you for your prompt reply!
        My alkalinity is very high and of course, so is my pH.. Oddly enough, the chlorine level is right on level where it should be. I read you’re supposed to correct alkalinity first, but do they even have alkaline decreasers? I did use the pH decreaser because that was all I was provided.
        I went ahead and added more chlorine and pH decreaser for now per your suggestion.

        • There is not a product an alkalinity decreaser- you will use pH decreaser to bring that down! Just make sure to follow the instructions and bring it down in the increments that the product suggests!

          Hopefully that will help! High pH and Alkalinity can definitely contribute to cloudy water!
