DescriptionA complete kit to measure and adjust pH. Tests pH levels from 6.0 to 7.6 and includes bottles of pH Up and pH Down to modify aquarium water pH to desired levels. 250 Tests per kit.Freshwater Deluxe pH Test Instructions:Why Test pH?pH is the measure of acidity of water. A pH reading of 7.0 is neutral. A pH higher than 7.0 is alkaline, and a pH lower than 7.0 is acidic. Maintaining the aquarium at the proper pH ensures optimal water quality.Testing Tips:This test kit measures pH from 6.0 to 7.6. Certain freshwater fish thrive at a pH above 7.5. Live-bearers, goldfish and African cichlids prefer a pH of 7.5. When keeping fish in this pH range, use Aquarium Pharmaceuticals High Range pH Test Kit.Directions for Testing pH:Read thoroughly before testing. Do not allow Test Solutions to get into aquarium.To remove childproof safety cap: With one hand, push red tab left with thumb while unscrewing cap with free hand.Fill a clean test tube with 5 ml of water to be tested (to the line on the tube).Add three drops of Indicator Solution, holding dropper bottle upside down in a completely vertical position to assure uniformity of dropsCap the test tube and invert tube several times to mix solution. Do not hold finger over open end of tube, as this may affect the test results.Determine the pH reading by matching the color of the solution against those on the pH Color Chart. The tube should be viewed against the white area beside the color chart. Color comparisons are best made in a well-lit area. The closest match indicates the pH of the water sample. Rinse the test tube with clean water after each use.Recommended pH Levels:A pH of 7.0 is ideal when keeping a community aquarium containing a variety of tropical fish. Goldfish should be kept in their own aquarium and prefer a pH of 7.5. Many fish, like angelfish and neon tetras, prefer a pH of 6.5 to 6.8. Mollies and swordtails thrive at pH 7.2 to 7.5. To raise or lower the pH of a freshwater aquarium, use Aquarium Pharmaceuticals pH UP or pH Down, following the directions on the container. Aquarium Pharmaceuticals Proper pH 6.5, 7.0, and 7.5 powders automatically adjust pH to the preset level.Frequency of Testing:The pH should be tested weekly, since natural materials in the aquarium (such as fish waste and decaying food) can cause pH changes. The minimum pH reading for this kit is 6.0 and the maximum is 7.6. Under extreme water conditions, readings below the minimum will read 6.0 and above the maximum will read 7.6. pH adjustments outside the range of this kit will not show any changes until the pH of the aquarium water is within the range of this kit.Danger:Corrosive C irritant XipH Up:Contains sodium hydroxideCauses burnsKeep locked up and out of the reach of childrenIn case of contact with eyes, rinse immediately with plenty of water (at least 15 minutes) and seek medical adviceAfter contact with skin, wash immediately with plenty of water.
