Directions for Calcium Test Kit
Red Sea’s Marine Care calcium test kit provides an easy measurement of Calcium with
a resolution of either 15 or 30 ppm as desired.
To measure Ca levels in 15 ppm resolution
Using the syringe provided, place exactly 10 ml of the water to be tested into the glass vial.
Add 10 drops of Calcium Reagent A and mix gently for 10 sec.
Proceed with the test as below
To measure Ca levels in 30 ppm resolution
Using the syringe provided, place exactly 5ml of the water to be tested into the glass vial.
Add 5 drops of Calcium Reagent A and mix gently for 10 sec.
Proceed with the test as below
Test as follows:
1. Add a leveled measuring spoon of Calcium Reagent B.
2. Close the vial with the cap and shake for 20 seconds. The test sample will now have the
titration start color as shown on the instruction card.
3. Add 1 drop of Ca reagent C and shake for 5 seconds. Continue to add Ca reagent C one
drop at a time (shake for 5 seconds after each drop) until the color of the sample in the
glass vile changes to the corresponding “end” color as shown on the instruction.
4. Count the number of drops required to reach the end color. Each drop of Ca reagent C
corresponds to 15 / 30 ppm of Calcium depending on the method you chose to follow.
Calcium levels adjustment
In order to adjust Ca levels to the correct levels it is highly recommended to use Red Sea’s
Foundation
™
Calcium+ on regular basis.
