Eliminate White Algae Biofilm In Hot Tub Water

How to eliminate white algae biofilm in hot tub water – this condition is a type of bio-film build-up in the pipes, presenting itself as white flakes similar to floating bits of tissue paper and can be caused by a lack of regular maintenance. Boosting the water with sanitizer does not always correct the problem: sanitizing products do not break down large matter and the flakes themselves can consume sanitizer. This will take several days to correct and remove and will require draining of the hot tub water. Draining could be required more than once depending on the severity of the problem. Do not use the hot tub during this process. We recommend Dazzle Genuine Watercare Products.
*Follow individual product label directions.

Step One – Shock the Hot Tub Water

1. Add 1 cup of your regular sanitizer treatment, ie: Dazzle Chlorine or Bromine Granules.
2. Remove hot tub cover completely, reduce heat and circulate for 24 hours, starting with
   system on high speed with all jets on, including neck jets and foot jets, with air controls
   open. Return to high speed as often as possible within the next 24 hours.
3. Remove filter and discard.

Step Two – Drain Procedure

1. Add 1 tablespoon of Ahh!some Plumbing & Jet Cleaner to clean out lines and remove
   excess debris. Follow instructions as per label.
2. After 24 hours, if there is any measurable sanitizer level, use Neutralizer sparingly as per
   directions to neutralize before dumping.
3. Drain the hot tub as per standard drain and fill procedures.

Step Three – Clean and Refill

1. Wipe down hot tub acrylic, underside of hot tub cover and any other products, ie: rubber
   ducks, floaters, thermometers, etc., that have come in contact with water over the past few
   months, with 50/50 bleach and water solution.
2. Refill hot tub and replace with new or clean filter.
3. Proceed with normal start-up procedure and add 1 cup of your regular sanitizer
   treatment, ie:Dazzle Chlorine or Bromine Granules, then maintain a 3-5 ppm level of
   sanitizer.

*Note: you may want to repeat one or more of these steps, depending on the severity of the problem.
