How to Kill Pink Algae in your swimming pool

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.

At a Glance








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.


Add Swamp Treat

Add one (1) bottle of Swamp Treat™ per 20,000 gallons of pool water. 



Brush the walls of the pool. One good brush over the wall should be fine. 



Add approximately 2 pounds/gallons of chlorine pool shock per 10,000 gallons – cascading it around the pool.


Run the Filter

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.

What You’ll Need

  • Swamp Treat™ Rescue Algicide
  • Brush Attachment
  • Vacuum Attachment
  • Pool Shock of your choice
  • Gloves (see Tips)

Extra Tips

  • Pink slime can lead to infections in open sores. Make sure to wear gloves to protect any cuts you may have on your hands.
  • Check the filter pressure every few hours and backwash as necessary. Your filter may clog quickly depending on how much pink slime you have.
  • Keep your filter running continuously to help get rid of the algae.
  • Back wash your filter when the filter pressure rises above 10 psi than normal.
  • Don’t pour shock directly on colored surfaces. This can discolor your surface.
