Although uncommon, pink algae in your pool can create a real headache. This type of bacteria can grow quickly and hide in hard to reach areas. Not to mention that it can infect open sores and wounds. Here we’ll show you how to get rid of pink pool slime fast and keep it from coming back.
Steps
hour(s)

Set your system to “vacuum to waste” and using your pool vacuum remove as much large debris and sludge from the bottom of the pool as possible.
Pink slime likes to grow in dark places – like behind pool lights and other fixtures. Make sure to remove as much pink slime as possible.
Check the filter pressure every few hours and backwash as necessary. Your filter may clog quickly, depending on the amount of pink slime you have.
Add one (1) pound of Swamp Treat™ per 20,000 gallons of pool water.

Brush the walls of the pool. A quick brush over the wall should be sufficient.
Add approximately 2 pounds/gallons of chlorine pool shock per 10,000 gallons – cascading it around the pool.
Don’t pour shock directly on colored surfaces. This can discolor your surface.

Set your system back to filter, and turn the pump on. Allow to filter for 24 hours. Continue to filter and backwash as necessary until pool clears up.
Despite its common name, “Pink Algae” is a misnomer; it is not an algae, but rather a bacterial infestation. The primary culprits are typically Methylobacterium or Serratia marcescens—bacteria that produce distinctive pink, red, or coral pigments to protect themselves from UV radiation.
Unlike green algae, these organisms form a heavy, gelatinous biofilm that feels slick to the touch. They have a specific affinity for PVC plastics, which is why you will frequently find them colonizing skimmer baskets, pool cleaners, solar covers, and vinyl liners rather than just floating in the water.
