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.\u003c\/p\u003e\u003cp\u003eRead the package label before use.
