1. Add with the syringe 10ml of water in the test vial.
2. Add to this 4 drops of PO4-1 reagent and swirl the test vial gently for 10 seconds.
3. Add to this 1 level scoop of PO4-2 reagent and swirl the contents gently for 30 seconds.
4. Place the open test vial on top of the color shart on a part of the chart which is white and compare the colors looking from the top. Read the corresponding phosphate content. An intermediate color corresponds to an intermediate phosphate content.
The phosphate values are in ppm Phosphate. If you prefer a reading in ppm Phosphate-Phosphor then divide the reading by 3 or use the table given below.
Should you require an even higher sensitivity then double the water sample and the reagents. The scale should then be divided by 2.
|ppm Phosphate||ppm Phosphate-Phosphor|
|0.25 (coral growth retarded)||0.08|
