Where can I find the record sheets for the documentation of my water analysis?
Have you lost your record sheets, already filled them all in or do you need them in another language?
With the following links you can quickly and easily print out your new record sheets with recommendations for the individual parameters at home and document the water analyses.
Why are there no colour charts for the JBL GH test, the JBL KH test, the JBL calcium test Ca and the JBL magnesium test Mg?
The following tests from the test range are so-called titration tests: 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
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
What can I do when the measured value of a water test falls outside the scale?
If one of your measurements reaches the end of the colour chart scale you can multiply the scale, by diluting the following 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.
Her’s how in greater detail:
JBL GH test kit: Instead of 5 ml use 10 ml aquarium water. Now 1 drop is equivalent to 0.5 dGH.
JBL KH test kit: 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.
JBL NH4/NH3 Ammonium/Ammonia test kit, JBL NO2 Nitrite test kit, JBL Fe Iron test kit and JBL Cu Copper test kit:
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 test kit, JBL SiO2 Silicate test kit, JBL PO4 Phosphate sensitive test kit and JBL Mg Magnesium test kit 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
JBL PO4 Phosphate test kit 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
JBL K Kalium test kit:
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

What is the shelf life of the JBL KH-Test ?
The JBL KH test has a shelf life of 3 years in the original sealed bottle.
The following is printed on the bottom of the packaging:
CH/B: 2251 (e.g.) = batch number
BBD: 05/13 (e.g.) = best-before date.
Please note that the best-before date does not apply for opened reagents. Exposure to atmospheric oxygen decreases the shelf life.
Do my water tests still work although they have been open for nine months?
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.
