Safely and quickly lower the pH in your freshwater aquarium for more acidic water conditions with API pH Down Aquarium Water Treatment. pH is the measure of acidic or alkaline water conditions. Water with a 7.0 pH level is considered neutral. Levels over 7.0 are considered alkaline, and levels under 7.0 are considered acidic. Different fish need different pH levels to stay healthy. For example, most freshwater fish thrive in levels between 6.5 and 7.5, but Cichlids and crustaceans require higher pH levels between 7.8 and 8.8. Levels that are too high, or too low, can cause stress, illness and death, so testing is crucial to the health of your fish. API pH Down Aquarium Water Treatment is designed to lower pH in water that tests at an undesirable level. It is fast-acting, colorless and easy to use. It will not cloud or color aquarium water, and because it's phosphate- and nitrate-free, it will not encourage algae growth.
