API® pH Down Adjuster Aquarium Water Conditioner for Aquarium pH Control

DESCRIPTION API pH Down lowers freshwater aquarium pH to keep it at the correct level. Use this product to make sure your aquarium's pH level is always where you want it to be. Features: Lowers freshwater aquarium water pH with a phosphate-free formulaDoes not promote algae growth with pH adjustments and is safe for plants and fishSlowly neutralizes alkaline substances that cause high water pHTest water weekly and use to correct pH level in freshwater aquariums Includes: Contains one (1) API pH DOWN Freshwater Aquarium Water pH Reducing Solution 4-Ounce BottleIntended Pet(s): FishProduct Dimensions: 1.5 in x 1.5 in x 5.375 inCapacity: 4 fl ozDirections: Determine the pH of aquarium water with an API pH TEST KIT. To lower pH, add 2 drops per U.S. gallon (3.8 L) of aquarium water. Take another pH reading before adding another dose. Note that some fish may be sensitive to pH adjustments greater than .2 in a 24 hour period, so changes of this magnitude she be executed with extreme care. Use the API pH TEST KIT weekly to accurately monitor pH. Then, when necessary, use pH DOWN to reduce pH levels in your aquarium. Tip: Some water is high in mineral ions, such as carbonate and bicarbonate, which strongly buffer aquarium water and can resist a pH change or cause "pH rebound." In these situations, repeated dosing may be necessary to lower pH.
