White water mold is a naturally growing fungus with a tissue paper-like substance. Its heavy, protective coating offers the organism with an extremely high level of protection. Even after it is destroyed, this type of mold can still re-contaminate.
White water mold can be found in a number of places, including:
- Pool ladders
- Skimmer Baskets
- Garden Hoses
Generally, WWM is caused by improper water and pool maintenance, environment or poor circulation. To prevent WWM, make sure to thoroughly brush and scrub the entire pool surface on a weekly basis. Try to expose the ladder, steps and rails to as much natural sunlight as possible as UV rays are natural oxidizers. Also, pour oxidizing chemicals into the skimmer to purge and clean the filtration lines of biofilm.
Pool toys and floats need to be regularly cleaned and the pool filter should be run at least 12 hours a day in order to prevent dead spots in the pool.
If you notice signs of mold along your pool, treatment must be thorough. Clean all affected surfaces as well as all visible WWM. Next, add the recommended dosage of algaecide to your pool and the shock pool with a triple dose. The filter should be running continuously at this point until the water is completely clear. Within the next 4-5 days, take a water sample and retest to be 100% certain that there is a healthy amount of alkalinity pH and calcium hardness.
