White Water Mold

 

What it is & what it looks like:

  • A naturally occurring fungus (this is NOT a form of Algae; it is animal not vegetable).
  • A white mucous or tissue paper-like substance frequently described as "noodle like".
  • Forms a heavy, protective coating providing the organism with an unusually high level of protection that is very resilient against halogen-based (chlorine, bromine) & non-halogen sanitizers or germicides.
  • Water mold thrives on the surface of PVC plastics including pipes & plumbing lines & air bubbler/blower lines
  • Can re-contaminate long after it appears that it has been destroyed
  • Small quantities can lead to a re-establishment of the problem
  • Caused by improper water & pool maintenance, environment, poor circulation
  • Prefers areas that are "dark" (not exposed to direct sunlight) & with "slow moving" water
  • Tends to be more common when using biguanides (soft swim, baquacil, etc.), and ofter starts or is heavily visable in ozone lines.

Prevention:

Prevention of "white spa mold" is preferred over treatment. Follow these steps to help prevent white water mold:

  1. Physically wipe & clean ALL spa & hot tub surfaces weekly, including recesses around all jets & underneath pillows.
  2. Expose ALL spa surfaces to as much sunlight as possible (sunlight & UV are natural oxidizers).
  3. When the water is changed use Spa System Flush or Swirl Away to break-up any build-up of bio-film in the pipes.
  4. Regularly add oxidizing chemicals into the skimmer to purge & clean the filtration lines of any bio-film.
  5. When adding make-up water from the garden hose, allow the water to run for 2 to 3 minutes before putting the hose into the spa.
  6. Regularly clean spa toys & floats.
  7. Regularly clean floating blanket and/or the underside of your cover.
  8. Chemically clean filter every 3 to 4 times a year.
  9. Add regular Maintenance dosages of "Shock".
  10. Run the filter a minimum of 6 hours daily to prevent "dead spots" in the water's circulation.
  11. Remember to clean & rinse the brushes, hoses & vacuums that you use to clean your spa.
  12. Keep the water balanced at all times. Recheck after heavy usage or rain or large "top-offs" of new water. Test the water at least 2 to 3 times per week.  Water balance refers to Free Available Sanitizer level, pH, Total Alkalinity, Calcium Hardness.

Treatment:

Treatment of "white water mold" MUST BE QUICK AND TOTAL! DON'T SKIMP!

  1. Clean all affected surfaces as prescribed above.
  2. Use a plumbing cleaner such as Spa System Flush or Swirl Away to break-up any build-up of bio-film in the pipes.
  3. Physically clean & remove all visible "white water mold".
  4. "Shock" the water with a triple or quadruple dose of sanitizer.
  5. Run filter 24 hours daily until water is clear & chlorine or bromine levels are maintained at a "higher" level.
  6. Chemically clean the filter.
  7. Maintain good water balance of pH, Total Alkalinity & Calcium Hardness
