As soon as the water shows a clearly visible pink coloration which remains constant stop adding the reagent. If the colouration stays for 60 seconds the “end” has been reached. Adding further reagent does not result in the deeper pink colouration of the colour chart.
The tests from the test range: JBL GH test, JBL KH test, JBL calcium test Ca and JBL magnesium test Mg, where the number of drops are counted until the colour changes and the counted value is multiplied by a value:
GH = number of drops = general hardness in °dH
KH = number of drops = carbonate hardness in °dH
CO2 = number of drops * 2 = CO2 in mg/l
Magnesium + calcium = number of drops * 120 = amount Ca + Mg in mg/l
Calcium = number of drops * 20 = amount Ca in mg/l
Magnesium = amount Ca+Mg from magnesium test - amount Ca in mg/l = magnesium in mg/l
If one of your measurements reaches the end of the colour chart scale you can multiply the scale by diluting later tests with distilled water (e.g. JBL Dest).
Here’s how to do it: dilute the sample with distilled water and carry out the test once more.
This works in detail as follows:
GH test: Instead of 5 ml use 10 ml aquarium water. Now 1 drop is equivalent to 0.5 dGH.
KH test: Instead of 5 ml use 10 ml aquarium water. Now 1 drop is equivalent to 0.5 dGH.
Note: when using 10 ml sample water the colour development is weaker with the first drops than with 5 ml sample water. Put the measuring container on a white underlay for a better readability.
NH4/NH3 ammonium/ammonia, NO2 nitrite, Fe iron and Cu copper:
2.5 ml sample + 2.5 ml dist. water: result times 2
1 ml sample + 4 ml dist. water: result times 5
0.5 ml sample + 4.5 ml dist. water: result times 10
NO3 nitrate, SiO2 silicate, PO4 phosphate sensitive and Mg magnesium freshwater:
5 ml sample + 5 ml dist. water: result x 2
2 ml sample + 8 ml dist. water: result x 5
1 ml sample + 9 ml dist. water: result x 10
PO4 phosphate koi high range:
2.5 ml sample + 2.5 ml dist. water: result x 2
1 ml sample + 4 ml dist. water: result x 5
K potassium:
7.5 ml sample + 7.5 ml dist. water: result x 2
3 ml sample + 12 ml dist. water: result x 5
1.5 ml sample + 13.5 ml dist. water: result x 10
K potassium in marine water:
1. Fill 10 ml of sample water with distilled water to 300 ml.
2. Follow the instructions for fresh water.
3. Multiply the test result by a factor of 30.
CO2 direct, Ca calcium and Mg+Ca magnesium+calcium: not required.
Basically a sealed test keeps longer than an open one. How much the shelf life is reduced depends crucially on the handling and the storage conditions of the reagents. It may happen that a reagent in a test that has been open for 9 months doesn’t indicate correctly any more. However, additional information is needed to answer this question properly.

Funktioniert einwandfrei!
Best test ever
Einfache Anwendung. Funktioniert wie die üblichen Tröpfchentest aus dem Hause JBL. Sehr genau.
