Sera Calcium Instruction

[mohawk]

Hi,

I just bought a Sera test kit for Calcium. For some reason, it didn't bring the instruction. Does anyone have the instructions for this kit (Ca)?

Thanks!

1. Rinse the measurment vial several times with the water you are going to test., and fill to the 5 ml mark.

2. Add 8 drops of reagent 1. Whirl the vial gently.

3. Add a level-filled spoon (supplied) of reagent 2. Whirl the vial gently until the powder has dissolved.

4. Add reagent 3 drop by drop and count the drops. Whirl vial gently after each drop untill the color turns from pink to lilac or blue.

5. Each drop is 20 ppm so if you used 20 drops to get to blue, 20 x 20 = 400 ppm
