Cold Plunge Water Cloudy or Foamy? Dit is wie je moet bellen

The water in your cold plunge tub turns milky, cloudy, or foamy within a day or two even though the filter is running. This is typically caused by bacteria blooming in low-chlorine cold water, body oils overwhelming the filtration, or biofilm building up on interior surfaces. A pool and spa technician can test the chemistry, deep-clean the plumbing lines, and set up a sanitation schedule that keeps the water crystal clear between drains.
