API® pH Down® slowly lowers the pH of pond water (making it more acidic) without harming delicate pond fish or aquatic plants. A high pH limits the ability of aquatic plants to absorb necessary nutrients. 

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