Determine the alkalinity concentration in water samples for aquarium and aquaculture







0 – 00 ppm as CaCO3


17.0 ppm per drop

Number of test

120 test


Titration method

Component in package

     1 bottle of Reagent#1, 2 bottle of Reagent#T, and 1 plastic tube

Shelf life

2 years


Instruction for use:

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

2. Add 1 drop of reagent#1 and mix well, the water sample turns to blue color.

3. Add reagent#T drop by drop with swirls gently and counts the total drops that change the solution color from blue to reddish-orange and record as A.

Total Alkalinity = A * 17 (ppm as CaCO3)
