pH is the measure of acidic or alkaline conditions of water. A value of 7.0 corresponds to a neutral pH. pH values about 7.0 are considered alkaline, and pH values below 7.0 are considered acidic. Different fish need different pH levels to be healthy. Check the pH level using a pH Test Kit.

pH UP is designed to raise the pH of aquarium water where testing has shown pH to be at an undesirable level. pH UP raises pH and makes aquarium water more alkaline. pH UP is fast-acting, colorless, easy to use and will not cloud or color the aquarium water. pH UP is phosphate free and nitrate free therefore will not encourage algae growth.

1. Use API’s Freshwater pH Test Kit to determine the pH of the aquarium.
2. To raise pH, add four drops of pH Up for every U.S. gallon (3.78 L) of aquarium water.
3. Take another pH reading before making the next addition of pH Up.
4. If fish are present in the aquarium, do not change the pH more than 0.2 in a 24 hour period (for example, from 7.0 to 7.2).

• For freshwater aquariums only.
• Do not raise ph by more than 0.2 in any 24 hour period.
• Keep out of reach of children.
