API pH Up, 4 OZ

The API® pH UP adjuster raises pH levels in your aquarium to make the water more alkaline when levels drop significantly. pH is a measure of the acidity or alkalinity conditions in water, where a value of 7.0 corresponds to neutral pH, values around 7.0 are considered alkaline, while values below 7.0 are considered acidic.

Different fish require different pH levels to be healthy, so it's important to test the water regularly to ensure pH levels are where they should be. The pH UP adjuster is fast-acting, colorless, easy to use, and will not cause cloudiness in aquarium water. Since it is free of phosphates and nitrites, the pH UP adjuster will not encourage algae growth.

Determine the pH level of the aquarium water using the API pH test kit. To raise the pH level, add 1 ml per 10 gallons of aquarium water.

Take another pH reading before adding another dose of pH UP adjuster.

Some fish may be sensitive to pH changes exceeding 0.2 within a 24-hour period, so such changes should be made with extreme caution.
