API pH UP Freshwater Aquarium Water pH Raising Solution for fish,4-Ounce Bottle, Brown

The API pH Up product is designed to raise the pH levels in fish tanks and can be used in tanks with invertebrates and snails. Users recommend shaking the bottle prior to use and pouring a capful into a glass of tank water to mix it up before adding to the tank, as it seems to work better this way. The product can continue to raise pH levels past the point that baking soda can, but the KH of brackish tanks might prevent it from lowering the pH. It is recommended to add 2 drops per gallon and wait about 30 minutes before re-testing the water. However, some users report that it did not work for them and they had to buy a powdered version instead. Overall, the product has both positive and negative customer reviews, although most users recommend it and would order it again.
