Pool Pink Slime (Bacteria)

Pink slime is a bacterial growth in pools and spas that appears as a pink or reddish-colored slime.

Causes of Pink Slime

How to Remove Pink Slime

  • Shock the pool with a high dose of chlorine.
  • Use a specialized pink slime treatment or algaecide.
  • Scrub affected areas thoroughly.
  • Improve water circulation and maintain proper sanitizer levels.
