pH Up or pH Down Water Conditioner

Fast-acting, colorless pH adjusters that will not cloud water. pH Up raises the pH of your aquarium, making water more alkaline. Great for African Cichlid aquariums and for freshwater tropical fish that prefer hight pH conditions.

pH Down lowers pH making water more acidic. Great for freshwater tropical fish and plants that prefer lower pH conditions. pH Up use 1/2 teaspoon per 10 gallons. pH Down, use 1/2 teaspoon per 20 gallons. 1 pint. For freshwater aquarium use.

• Use API's Freshwater pH test Kit to determine the pH of the aquarium.
• To lower pH, add two drops of pH Down for every U.S. gallon (3.78 L) of aquarium water.
• Take another pH reading before making the next addition of pH Down.
• If fish are present in the aquarium, do not change the pH more than 0.2 in a 24-hour period (for example, from 7.2 to 7.0).

General Information
Purpose and Benefits
pH Down is a liquid pH lowering product for freshwater aquariums. pH Down lowers pH by neutralizing carbonate hardness in the water.

Adjusting the pH to the proper level will improve fish health, disease resistance, coloration and breeding. While many common aquarium fish will live in water with a pH range of 6.8 to 7.5, a pH of 7.0 is ideal for a community aquarium containing a variety of freshwater fish. Live bearers like mollies and swordtails prefer a higher pH of 7.2-7.6. Acid-loving fish such as angelfish and neon tetras prefer a lower pH of 6.5-6.8.

Each dose of pH Down neutralizes some of the carbonate hardness and lowers the pH. The pH may rebound up to the original pH if the carbonate hardness is high. Several consecutive treatments with pH Down may be necessary to lower pH, but if there are fish present in the aquarium, the pH should not be changed more than 0.2 in a 24-hour period. The number of doses required to lower the pH will depend on the carbonate hardness level and the desired pH level. An aquarium with low carbonate hardness may require one treatment with pH Down while an aquarium with a high carbonate level will require several.

pH Up
Directions for Use:

• Use API’s Freshwater pH Test Kit to determine the pH of the aquarium.
• To raise pH, add four drops of pH Up for every U.S. gallon (3.78 L) of aquarium water.
• Take another pH reading before making the next addition of pH Up.
• 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).

General Information
Purpose and Benefits:

pH Up is a liquid pH raising product for freshwater aquariums. By neutralizing acidic substances in the aquarium, pH Up effectively makes the water more alkaline. The pH may rebound down to the original pH depending on the level acid in the aquarium. Several consecutive treatments with pH Up may be necessary to adjust pH to the desired level, but if there are fish present in the aquarium, the pH should not be changed more than 0.2 in a 24-hour period.

While many common aquarium fish will live in water with a pH of 6.8 to 7.5, a pH of 7.0 is ideal for a community aquarium containing a variety of freshwater fish. Live bearers like mollies and swordtails prefer a higher pH of 7.2-7.6. Acid-loving fish such as angelfish and neon tetras prefer a lower pH of 6.5-6.8. Making a partial water change (10-15%) will also remove some of the acids and help stabilize the pH. Adjusting the pH to the proper level will improve fish health, disease resistance, coloration and breeding.
