General instructions for testing
1. Before carrying out any water testing always check the salinity and make
adjustments as necessary. If you have made adjustments to the water wait 10
minutes for the water parameters to stabilize. (e.g. 1 ppt increase in salinity due to
evaporation of fresh water will result in approximate increases of 13ppm Ca)
2. Before testing, clean the glass vial and the large syringe by rinsing with the water
to be tested.
3. After testing rinse all syringes and vials with RO or distilled water before storing.
If vials are left unwashed a residue can form that will affect the results of future
tests. Use a slightly acidic solution such as vinegar to remove the residue.
4. In order to ensure an accurate drop size always hold reagent bottle vertically
above the test vial, and gently squeeze out each drop.
5. Close all reagents tightly immediately after use.
6. The test reagents are stable up to the date stated on the pack when stored closed
between 15 – 25 °C.
7. Store the reagents and color card in the box to prevent damage from prolonged
exposure to light.
