API® pH Up® slowly raises the pH of pond water (making it more alkaline) without harming delicate pond fish or aquatic plants. A low pH can stress pond fish and suppress the activity of a biological filter. 

  • Slowly neutralizes acidic substances that cause high pH (mineral leaching, soil runoff & decomposing waste)
  • Contains no algae-promoting phosphates
