Salifert Calcium Test Kit
Salifert Calcium Test Kit is an easy-to-use test kit with a single reagent and powder only. Calcium is a major constituent of calcareous algae, the skeletal material of hard corals, and the skeletal needles of soft/leather corals. Calcium also fulfills many biological functions.
Too low calcium concentration retards coral and calcareous algae growth. In a healthy aquarium, the growth and multiplication of corals, calcareous algae and other organisms can result in calcium depletion.
To maintain a stable environment it is important that the calcium content should not fluctuate by more than 15 mg/L from the optimum range of 420 – 450 mg/L so regular testing should be carried out. This means that any calcium test used should have an accuracy of significantly less than 15mg/L otherwise it will be difficult to monitor such fluctuations. The Salifert Calcium Test Kit measures in steps of 5 mg/L and has an accuracy of 10 mg/L.
The Salifert Calcium Test Kit can perform approx. 50 – 100 tests.
Directions for use:
Add with a syringe 2ml of water in the test. For a lower resolution but more tests per kit, use 1ml instead of 2ml.
Add 1 spoon of Ca-1 (low resolution approx. 1/2 spoon) do not mix yet.
Put the plastic tip firmly on the 1ml syringe. Draw into the syringe the Ca-2 reagent (ensure that the end of the plastic tip is constantly submersed in the Ca-2 reagent) till the lower end of the black part of the piston is exactly at the 1.00 mark.
Add 0.6ml of the reagent all at once (lower end of piston at 0.4 ml mark). Swirl for 5 seconds. The colour should now be pinkk. For the low resolution mode 0.3 (lower end of piston at 0.7 ml mark)
Continue by adding Ca-2 dropwise to the water in the test tube.
Swirl after each drop a second or 2.
Continue with this until the colour changes from pink to blue.
Once the colour changes to purple, you will need to add 1 – 2 drops to optain the blue colour.
Hold the syringe with the tip facing upward and read the position of the, now the upper end, of the black part of the piston. The syringe has graduations of 0.01 ml. Read the calcium value from the table.
If you have chosen the lower resolution mode of the Salifert Calcium Test Kit, then multiply the calcium value from the table by 2.
