API® Pond pH Down® 16ozAPI® Pond pH Down® 16oz

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. 


API® Pond pH Up® 16ozAPI® Pond pH Up® 16oz

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. 


Aquascape® Alkalinity Booster with Phosphate BinderAquascape® Alkalinity Booster with Phosphate BinderAquascape® Alkalinity Booster with Phosphate Binder increases the overall KH/pH and Alkalinity of the pond, and it dissolves completely and easily into pond water. This lab-tested, pharmaceutical grade pH booster is phosphate and ammonia free.
BioSafe GreenClean pH UP and pH DOWN - pH BalancersBioSafe GreenClean pH UP and pH DOWN - pH Balancers

Keeping pH level in a neutral range is essential for the health of aquatic life, plants, and the pond ecosystem. An unbalanced pH level suppresses the proper amount of nutrients aquatic plants need to thrive and is a major cause of fish stress and disease. GreenClean pH UP and GreenClean pH DOWN slowly raise or lower the pH of pond water, making it more alkaline or acidic.

      Koi Kichi kH KickerKoi Kichi kH KickerKoi Kichi kH Kicker boosts the pond nitrogen cycle by providing necessary alkalinity, which helps prevent pH swings. This reduces potential health hazards for fish. Acts as a pH buffer as well.
      Microbe-Lift® 7.5 pH Buffer StabilizerMicrobe-Lift® 7.5 pH Buffer Stabilizer
      Microbe-Lift® 7.5 pH Buffer Stabilizer safely buffers pH levels and prevents wide pH swings. Specifically formulated to control the event of fish toxicity due to potential overdosing. Provides necessary alkalinity for nitrification.
      Microbe-Lift® KH Alkalinity Bio-Active BoosterMicrobe-Lift® KH Alkalinity Bio-Active Booster
      Microbe-Lift® KH Alkalinity Bio-Active Booster provides the essential alkalinity for nitrification. When pond carbonate levels fall below the necessary level, nitrification will stop and will fail to start again. With insufficient KH levels, pH levels will also vary and be difficult to control.

            UltraClear® pH Higher by ABI Inc.UltraClear® pH Higher by ABI Inc.

            UltraClear® pH Lower reduces the pH in aquatic systems. Most ponds and aquariums have desired pH between 6.0 and 8.5. Because most ponds and aquariums are closed systems, pH may drift away from healthy levels as time goes on. Whether you're starting out your system on the right foot, or maintaining and correcting an existing system, the easiest and safest way to control pH is with pH balance chemicals like UltraClear pH Lower and pH Higher.
