Determine the calcium & magnesium in water samples for aquarium and aquaculture

 

 

Specification:

Range	Ca 40 – 800 ppm as Ca Mg 50 – 1725 ppm as Mg
Resolution	Ca 40.0 ppm per drop Mg 50.0 ppm per drop
Number of test	120 test
Method	Titration method
Component in package	1 bottle for reagent #1 – reagent #3, 2 bottle of reagent #T, and 2 plastic tube
Shelf life	2 years

 

Instruction for use:    

Calcium

1. Rinse the test vessel several times with the water to be tested and fill to the 10 mL. mark.

2. Add 2 drops of reagent #1 and also 2 drops of reagent #2, then swirl gently. Solution will be pink color.

3. Drop reagent #T drop by drop with swirls gently. After color change from pink to blue. Counts and record as A.  

Magnesium

1. Rinse the test vessel several times with the water to be tested and fill to the 5 mL. mark.

2. Add 1 level spoon of powder #3 and swirl gently, the solution will be orange color.

3. Drop reagent #T drop by drop with swirls gently and counts the total drops that change the solution color from orange to green and record as B.

 

Ca = A * 40 (ppm)

Mg = (B – A/2) * 50 (ppm)

Total hardness= B * 200
