CALCIO TEST
MARINE AQUARIUM
Keeping the tests easy to use was a big concern for us, and our chemists were able to get the calcium test in just two steps. Having clear color changes in the titration was also key, to help eliminate user confusion as to whether they were reading the test accurately.
Each test uses a two-part chemical reaction and a syringe to add water to the final color. 50 calcium tests are supplied in the box.
Our way of testing for Ca is slightly different and is based on direct titration where we add seawater to the chemical solution. Our preferred solution reacts first to Ca and then to Mg. It then reacts to the colored metal ion indicator and this is the color changing stage. The color of the indicator is changing very clearly from pink to blue.
CALCIUM TEST INSTRUCTIONS - Just 2 Steps
1. Using the 3 ml syringe, add 2 ml of Ca-1 to the test vial.
2. Add a 0.15 ml flat scoop of Ca-2 powder to the test vial and shake.
• The solution should look like this:
3. Using the 1 ml syringe, firmly place the plastic tip and draw up the aquarium water until the bottom end of the black rubber of the syringe is exactly at the 1.00 ml mark. Before this step, make sure the plastic tip is empty of liquid and is immersed in the water at all times to prevent air from entering the syringe.
• A layer of air between the liquid and the black part of the syringe is normal and will not affect the result. (The normal air layer you should see is equal to 0.1 ml.)
4. Start adding aquarium water to the test vial one drop at a time, swirling slightly after each drop until the solution looks like this:
Caution: Before using the test vial, make sure it is washed with RO water only and dry it with soft paper.
• If the solution in the test vial does not reach this color and you have used all the aquarium water in the syringe, go back to step 3 (this means that the calcium concentration is less than 320 ppm).
• If after adding another 1.00 ml of water a second time, the color has still not changed, this means that the calcium concentration is less than 160 ppm.
The fastest test can be achieved without the plastic tip with a potential error of 3%.
5. Note the position of the lower black part of the syringe (each division corresponds to 0.01 ml) and obtain the calcium concentration from Table 1. Readings should be taken at the position of the lower black rubber end of the syringe.
• If you need to return to step 3 a second time, use Table 2 to obtain the calcium concentration. NSW calcium is approximately 400 PPM. Our recommendation is to maintain calcium levels in the aquarium between: 390-440.
