As phosphate increases, so does the chance of having unsightly algae and green water blooms. Test reads 0 to 10 mg/ or parts per million (ppm) of phosphate in fresh or salt water. INSTRUCTIONS Use Instructions: To remove childproof safely cap: push down on cap while turning. 1. Fill a clean test tube with 5 ml of water to be tested (to the line on the tube). 2. Holding the bottle vertically, add 6 drops from Phosphate Test Solution #1. cap the test tube and shake vigorously for 5 seconds.3. Now, holding the bottle vertically, add 6 drops from Phosphate Test Solution #2. Note: Test Solution N2 is a very thick solution and may require increased pressure to release drops.4. Cap and shake the test tube vigorously for 5 seconds. 5. Wait 3 minutes for color to develop.6. Read the test results by compering the color of the solution to the appropriate Phosphate Color Card (choose either Freshwater are Saltwater). The tube should be viewed in a well-lit area against the white area of the Card. The closest match indicates the ppm (mg/L) of total phosphate (P0,3-) in the water sample. Rinse the test tube with clean water after use. Storage Instructions: Store in a cool, dry, well-ventilated area.
