Slowly lower the pH of your pond water to make it more acidic using API Pond pH DOWN. This product slowly neutralizes alkaline substances that cause high pH, which limits the ability of aquatic plants to absorb necessary nutrients. pH DOWN is safe for pond fish and aquatic plants, and contains no algae-promoting phosphates.
