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 GH. KH, Mg /Ca saltwater and CO2 direct?
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
I have lost my colour chart. Can I download the colour chart for the test?
The colour cards are not available for download on the JBL website. The absolutely accurate colour reproduction that is required can only be achieved using a printer which can be re-calibrated before each printout. Most privately used printers are not accurate enough for this.
You will find the colour chart bundle as a spare part on the respective product page and in the spare parts shop under: https://www.jbl.de/en/products/detail/8732/jbl-proaquatest-assortiment-color-chart
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 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
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.
Which scale applies for my aquarium? My test has two or three control fields with fish and recommendations.
We repeatedly receive questions regarding the symbols on the water test. The hobby areas cannot be clearly assigned to the scales for analysis. There are three symbols to make the hobby areas on the colour charts clear:
Discus = fresh water
Emperor = salt water
Koi = garden pond
In the following, you will find a list which assigns the scale for analysing the results from measurements in the hobby area and explains the symbols: The scales are described from the top to the bottom here.
NO3: salt water, fresh water, garden pond
pH 6.0 – 7.6: fresh water, garden ponds
pH 7.4 – 9.0: salt water, fresh water, garden pond
Fe: fresh water, garden pond
The following JBL tests have a uniform scale for all 2 or 3 hobby areas for analysis of the results from the measurements, as differentiation is no longer necessary:
