pH Up: API POND pH UP slowly raises the pH of pond water, making it more alkaline, without harming delicate pond fish or aquatic plants. It slowly neutralizes acid substances that contribute to low pH, which can stress pond fish and suppress the activity of your pond’s natural biological filter.
pH Down: API POND pH DOWN slowly lower the pH of your pond water to make it more acidic using API® POND pH DOWN pH adjuster. This product slowly neutralizes alkaline substances that cause high pH, which limits the ability of aquatic plants to absorb necessary nutrients. POND pH DOWN pH adjuster is safe for pond fish and aquatic plants, and contains no algae-promoting phosphates.
