Is your hot tub water looking a little off? If you’re noticing cloudy water, there are a number of potential causes, and each requires a different solution. Read on to learn more about what makes hot tub water look cloudy and how to fix it.
While the effect of many problems is the same, it’s important to identify and treat the source issue to avoid a recurrence. The first step is to check your water for a variety of causes, such as:
- A dirty filter. The first test for any hot tub water problem is to examine its filters. The fix may be as simple as cleaning your filter in cleaning solution, washing it, and returning it to its original setting. If you use disposable filters, replace the existing one. A clean water filter will ideally clear away the cloudiness within the next few hours.
- An unbalanced pH. If your water is too alkaline or too acidic, it may develop a cloudy appearance. Calcium hardness also contributes to this problem. Test your water for alkalinity, pH, and calcium levels, and use balancing products to adjust.
- Chlorine or Bromine. Many hot tub owners prefer bromine or chlorine for killing off microorganisms and algae, but these solutions can cause damage to skin, hair hot tub parts and hot tub covers. We recommend switching to PristineBlue and pay closer attention to your water’s pH level.
- Dissolved contaminants. If you enter your hot tub wearing skin lotion, body butter, or other outside products, you’re actively contributing to cloudy water. To prevent this problem, rinse yourself off before entering the tub and tie up any long hair. If the water is already contaminated, use a shock or clarifier to rid the tub of buildup.
- Water circulation. If you have switched from traditional rigid foam spa covers, to a custom made hot tub cover from SpaCap.com, you’ll need to change your hot tub to run on the timer rather than the thermostat. Under a foam cover, the water would cool down faster and the thermostat would kick the pump on to re-heat the spa water. The spa water would circulate while it was being heated. Under a SpaCap hot tub cover, the water won’t cool down enough to have the pump run long enough to circulate the water to keep it clear. Switching the spa to run on the timer will allow the water to circulate for two to three hours at a time for two to three times per day and only heat the water as it needs to during that time. You’ll still save money because you’ll be heating the water less often but circulate it enough to keep clear.
If all else fails, it may be time to empty the tub and refill it. Before refilling, ensure the tub itself is clean and free of mineral deposits. Start again with fresh water.
