sera Calcium test for marine aquariums - Calcium-Test (112856)

Sera Calcium-Test (calcium test for marine aquariums) This test allows for easy and precise control of calcium levels with a range of 20 mg/l. A stable calcium level is essential for the growth of corals, aquatic plants, and invertebrates. In nature, the calcium content is approximately 410 mg/l. In a marine aquarium, the optimal level is 400–450 mg/l. Regularly check this value using the Sera Calcium-Test. To increase the calcium level, use Sera Marine Component 1+2. Test procedure 1. Preparation: shake the reagents before use. Rinse the cuvette with the water to be tested and fill it up to the 5 ml mark. Wipe the cuvette dry. 2. Adding reagents o Add 8 drops of reagent 1, shaking gently until a uniform state is reached. Turbidity does not affect the result. o Add 1 scoop of reagent 2 (white powder), stirring the cuvette carefully until the contents are dissolved. o Add reagent 3 drop by drop, counting the drops. After every 5 drops, wait to equalize the pressure in the bottle. Turn the cuvette slightly after each drop. 3. Completing the test: stop when the color changes from pink through violet to blue and remains so for 30 seconds. Multiply the number of reagent 3 drops by 20 to obtain the calcium level (mg/l). Example: 15 drops × 20 = 300 mg/l. Store at room temperature, protect from light.
