What it is & what it looks like:
Watch the video
a naturally occurring bacterium (of the newly formed genus Methylobacterium)
(this is NOT a form of Algae, it is animal not
Pink-pigmented, forms a heavy, protective slime coating providing the organism with an unusually high level of protection, methanol consuming,
oftentimes found WITH White Water Mold
Slime is very resilient against halogen-based
(chlorine, bromine) as well as non-halogen sanitizers or germicides and can remain a contaminant even after treatment.
This is NOT a biguanide problem only! Pink slime can & does occur in
chlorine & bromine pools as well.
The Pink Slime bacterium has an affinity for the matrix that exists on the surface of PVC plastics
(it likes it); it will attach itself to & inside of the matrix, allowing it to re-contaminate long after it appears that it has been destroyed (includes pool toys, floats, ladders, steps, fountains, automatic pool cleaner parts, skimmer baskets, weirs, directional fittings, garden hoses, etc.).
Small quantities can lead to a re-establishment of the problem.
It is generally caused by improper water & pool maintenance, environment, poor circulation.
Pink Slime prefers areas that are "dark" (not exposed to direct sunlight) & with "slow moving" water
** in another industry, medical technology, this bacterium occurs
regularly in laboratory tubing
Pink Slime & White Water Mold IS NOT CAUSED BY
USING BIGUANIDES (Soft Swim, Baquacil, Polyclear, etc.)!
It is an environmental issue.
in mind that Pink Slime CAN be physically removed (comes off with brush or
fingers). If what you think is Pink Slime, but appears to be more PURPLE &
isn't removed by brushing, you have another problem called Purple Cyanurate.

Prevention of "pink slime" is preferred over treatment. Follow these steps to help prevent pink slime:
1. Physically brush & clean ALL Pool surfaces weekly, including ladder steps (especially underneath each step) & rails
2. Expose ALL pool surfaces to as much sunlight as possible (sunlight & UV are natural oxidizers)
3. Remove the lid from the skimmer to allow sunlight into the basket for several hours each day ** INGROUND POOLS MUST USE EXTREME CAUTION in doing this in order to avoid a person falling into or otherwise injuring themselves due to an open skimmer.
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 pool.
6. Regularly clean pool toys & floats (use Stow Away)
7. Regularly clean pool solar blanket (use Stow Away)
8. Chemically clean pool filter every 4 to 6 weeks (use Strip Kwik, Kleen It or Soft Swim® Filter Cleaner)
9. Add regular Maintenance dosages of "Shock" & Algicide every 2 to 3 weeks as prescribed.
10. Use Optimizer Plus as a preventative measure
11. Run the filter a minimum of 12 hours daily to prevent "dead spots" in the pool
12. Remember to clean & rinse the brushes, hoses & vacuums that you use to clean the pool 13. Leave as much of your pool equipment exposed to the sun
14. Keep the water balanced at all times. Recheck after heavy usage or rain or large "top-offs" of new water. Water balance refers to Free Available Sanitizer level, pH, Total Alkalinity, Calcium Hardness.
Treatment of "pink slime" MUST BE QUICK AND TOTAL! DON'T SKIMP!
1. Clean all pool & affected surfaces as prescribed above.
2. Physically clean & remove all visible "pink slime"
3. Add an initial dosage of algicide to the pool*
4. "Shock" the pool with a triple or quadruple dose*
FREE brochure to learn about shocking.
5. Run filter 24 hours daily until water is clear & halogen or peroxide levels are maintained at a "higher" level*
6. Chemically clean the filter
7. Bring in a fresh water sample about 4 days later for a retest & evaluation
8. Maintain Optimizer Plus levels
9. Maintain good water balance of pH, Total Alkalinity & Calcium Hardness

To "cure" the problem, take a look at
AquaFinesse Pool Pucks.
recent customer told us about AquaFinesse...
"Ron. I am so impressed with you and your company's willingness to help and
educate pool owners, I went into the local pool store to buy a corner brush
because I forgot to order it from you last week and the girl said they don't
make anything like that (wow) and got upset when I asked about pink slime she
insist that if you just over chlorinate you will get rid of it. I use Baquacil
so chlorine won't work for me if it will work at all.
"I have been battling pink slime since I started topping
my pool off with garden hose and now know why many thanks to you. Two days
after first dose of aquafiness my pool look and feels so much better."
