Fritz Wide Range PH Test Kit

Directions & Dosage To remove childproof safety cap, push down while turning. DO NOT allow Test Solutions to get into aquarium. Fill a clean test tube with 5 ml of water to be tested (to the line on the tube). Add 3 drops of pH Reagent, holding dropper bottle upside down in a completely vertical position to ensure uniformity of drops added to the water sample. Cap the test tube and gently shake several times to mix solution. Attention! Always use the cap. Avoid skin contact as this may affect the test results. Immediately match the color of the solution against those on the pH chart to determine pH. Be aware that freshwater and saltwater results are different so ensure you are reading correct result. For best results the tube should be viewed against the white area beside the color chart in a well-lit area with a light source behind you. The closest match indicates the pH in the water sample. Rinse the test tube with clean water after each use. To raise pH, use Fritz pH Higher or Fritz pH Neutralizer. To lower pH, use Fritz pH Lower or Fritz pH Neutralizer. Always limit any changes in pH to 0.2 units per day when fish are present in the water being treated.
