Hints to clean up cloudy hot tub water

We get a lot of calls regarding cloudy hot tub water. Especially at this time of year, when the hot tub is getting increased use for social reasons and the bather load rises, it’s easier to get enough extra “stuff” introduced to the hot tub that can create cloudiness. There are a number of things you can do to guard against this issue. Here are our top recommendations.

  • Check sanitizer levels before the tub is used. When you know there are going to be extra folks using the tub, check the sanitizer with test strips prior to the get together. If you need a little extra sanitizer in the water, be sure and add it about two hours prior to use so it won’t cause anyone any discomfort. If you have an ACE Salt System, you might want to up your Output Level one or two settings to increase sanitizing while the gathering is going on. (Be sure to drop the level back to your normal setting the next day.)
  • After a long soaking party, add an extra dose of your sanitizer and shock and run your jets for at least a half hour to forty-five minutes. That will help eradicate any extra bacteria and prevent it a chance to start thriving—which could create cloudiness. After performing this exercise, be sure and clean the filters well.
  • Speaking of filters, how OLD are yours?? Filters should get changed on a regular basis. If you have one filter in your tub, best to change at least once every one to two years. If you have regular Hot Spring filters (three or more in your tub), they should be replaced every two to three years. If you have Hot Spring’s exclusive Tri-X filters, they only need to be replaced every four to five years. Don’t forget: All filters should be cleaned with filter cleaner monthly (not just hosed out with water, thank you very much). That’s regardless of use, too.
  • Check your tub’s alkalinity & pH levels. If your alkalinity is starting to get high, it’s going to be harder to keep your water balanced and the opportunity for cloudiness to crop up. Alkalinity readings of 180 or more indicate your tub needs a fresh batch of water. pH that is not neutral (especially if it gets high) can also cause cloudiness. Sometimes just correcting pH & alkalinity levels will solve cloudy water without adding anything else.
  • Add clarifier weekly. This is a terrific way to make sure your water stay bright. Two ounces of SeaKlear’s Natural Clarifier is excellent to keep your water clear and help keep foam at bay too.
  • Check your ozone system. Properly working ozone helps your tub stay free of contaminants and really cuts down on water care issues. Your ozone system will normally only last up to three years. (Bubbles do not mean ozone is present!) Ozone systems should also be cleaned twice a year for optimal performance. If your ozone is older than three years, it’s time for a new system.
  • If you use a silver ion cartridge, make sure it’s replaced every four months, regardless of use! Your silver ion cartridge is in play 24 hours a day, whether the tub is in use or not. Silver is a terrific neutralizer of bacteria, and works in tandem with your ozone and other water care products to keep your water healthy, safe and crystal clear.
