Product information

Healthy aquarium/healthy pond with conditions close to nature
The right water values depend on the fish stock and the plants in the aquarium/pond. Even if the water looks clear it can be contaminated. With bad values diseases or algae can appear in the aquarium/pond. To maintain a healthy aquarium/pond with conditions close to nature it is important to check and adapt the water values regularly.

For each water analysis JBL provides water tests in the form of quick tests or colour change tests. These determine a certain value or several values in one go. With these water tests you can recognise algae problems and negative nitrate, nitrite, potassium, magnesium values etc.

Why test?
In an aquarium, phosphate primarily enters the water as a result of the digestive processes of the fish or in the form of food remains. In ponds, phosphate primarily enters the water as a result of leaves and dying pond plants/algae. If conditions are unfavourable, the phosphate levels may reach values that are sometimes 100 times higher, and more, than natural levels. Undesirable algae will then multiply exponentially as an inevitable consequence.

Recommended phosphate values:
Freshwater aquarium (community aquarium): 0-0.4 mg/l
Lake Malawi/Lake Tanganyika aquarium: 0-0.4 mg/l
Plant aquarium with few fish (aquascaping): 0.1-1.5 mg/l
Marine aquarium: 0-0.1 mg/l
Pond: <0.05 mg/l

FAQ
Where can I find the record sheets for the documentation of my water analysis?

Have you lost your record sheets, used them all up, or need them in another language?
In the appendix of this FAQ you will find PDF files for printing them out in German, English and French.

What happens if I use the wrong side of the spoon for the powder?

Your test result will remain clear or appear slightly yellow, although phosphate may be present. If your test kit has not expired or has been open for more than 9-12 months, this is a clear indication that you have used the wrong side of the spoon.
The small side of the spoon should only be levelly filled and is in the place normally used to hold it. For clarification, take a look at the picture below.

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 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

JBL CO2 direct test kit, JBL Ca Calcium test kit and JBL Mg+Ca Magnesium+Calcium test kit:
not required

Why does the JBL Phosphat Test sensitive contain such a small amount of Reagent 1 ?

Only a small measuring spoon (the narrow end of the enclosed double spoon) of Reagent 1 is required.
